An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a "double fetch" vulnerability. NOTE: a third party reports that this is unexploitable because the doubly fetched value is not used

An update of the linux package has been released.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14354-1 advisory.

  - ** DISPUTED ** An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a     denial of service or possibly have unspecified other impact by changing the value of ioc_number between     two kernel reads of that value, aka a double fetch vulnerability. NOTE: a third party reports that this     is unexploitable because the doubly fetched value is not used. (CVE-2019-12456)

  - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in     Marvell WiFi chip driver.

It     can occur with FUSE requests.(CVE-2019-11487)The     coredump implementation in the Linux kernel before     5.0.10 does not use locking or other mechanisms to     prevent vma layout or vma flags changes while it runs,     which allows local users to obtain sensitive     information, cause a denial of service, or possibly     have unspecified other impact by triggering a race     condition with mmget_not_zero or get_task_mm calls.
    This is related to fs/userfaultfd.c, mm/mmap.c,     fs/proc/task_mmu.c, and     drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)A     n issue was discovered in the Linux kernel before     5.0.7. A NULL pointer dereference can occur when     megasas_create_frame_pool() fails in     megasas_alloc_cmds() in     drivers/scsi/megaraid/megaraid_sas_base.c. This causes     a Denial of Service, related to a     use-after-free.(CVE-2019-11810)An issue was discovered     in the Linux kernel before 5.0.4. There is a     use-after-free upon attempted read access to     /proc/ioports after the ipmi_si module is removed,     related to drivers/char/ipmi/ipmi_si_intf.c,     drivers/char/ipmi/ipmi_si_mem_io.c, and     drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)A     flaw was found in the Linux kernel's handle_rx()     function in the [vhost_net] driver. A malicious virtual     guest, under specific conditions, can trigger an     out-of-bounds write in a kmalloc-8 slab on a virtual     host which may lead to a kernel memory corruption and a     system panic. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out. Versions from     v4.16 and newer are vulnerable.(CVE-2018-16880)An issue     was discovered in rds_tcp_kill_sock in net/rds/tcp.c in     the Linux kernel before 5.0.8.

Versions from v4.18 and newer are     vulnerable.(CVE-2019-3819)A flaw was found in the Linux     kernel's vfio interface implementation that permits     violation of the user's locked memory limit. If a     device is bound to a vfio driver, such as vfio-pci, and     the local attacker is administratively granted     ownership of the device, it may cause a system memory     exhaustion and thus a denial of service (DoS). Versions     3.10, 4.14 and 4.18 are vulnerable.(CVE-2019-3882)An     infinite loop issue was found in the vhost_net kernel     module in Linux Kernel up to and including v5.1-rc6,     while handling incoming packets in handle_rx(). It     could occur if one end sends packets faster than the     other end can process them. A guest user, maybe remote     one, could use this flaw to stall the vhost_net kernel     thread, resulting in a DoS scenario.(CVE-2019-3900)In     the Linux Kernel before versions 4.20.8 and 4.19.21 a     use-after-free error in the 'sctp_sendmsg()' function     (net/sctp/socket.c) when handling SCTP_SENDALL flag can     be exploited to corrupt memory.(CVE-2019-8956)A flaw     was found in the Linux kernel's implementation of ext4     extent management. The kernel doesn't correctly     initialize memory regions in the extent tree block     which may be exported to a local user to obtain     sensitive information by reading empty/uninitialized     data from the filesystem.(CVE-2019-11833)An issue was     discovered in drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference.(CVE-2019-12382)An issue was     discovered in the efi subsystem in the Linux kernel     through 5.1.5. phys_efi_set_virtual_address_map in     arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory     allocation failures. NOTE: This id is disputed as not     being an issue because ?All the code touched by the     referenced commit runs only at boot, before any user     processes are started. Therefore, there is no     possibility for an unprivileged user to control     it.(CVE-2019-12380)An issue was discovered in the Linux     kernel before 5.2.3. An out of bounds access exists in     the function hclge_tm_schd_mode_vnet_base_cfg in the     file drivers     et/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.(CVE-2019-     15925)An issue was discovered in     dlpar_parse_cc_property in     arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6.

There is a net/ipv4/tcp_input.c signed integer     overflow in tcp_ack_update_rtt() when userspace writes     a very large integer to     /proc/syset/ipv4/tcp_min_rtt_wlen, leading to a denial     of service or possibly unspecified other impact, aka     CID-19fad20d15a6.(CVE-2019-18805)A flaw was found in     the way PTRACE_TRACEME functionality was handled in the     Linux kernel. The kernel's implementation of ptrace can     inadvertently grant elevated permissions to an attacker     who can then abuse the relationship between the tracer     and the process being traced. This flaw could allow a     local, unprivileged user to increase their privileges     on the system or cause a denial of     service.(CVE-2019-13272)An issue was discovered in     ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux     kernel through 5.1.5. There is an unchecked kmalloc of     new_ra, which might allow an attacker to cause a denial     of service (NULL pointer dereference and system crash).
    NOTE: This has been disputed as not an     issue.(CVE-2019-12378)An issue was discovered in     ip_ra_control in net/ipv4/ip_sockglue.c in the Linux     kernel through 5.1.5. There is an unchecked kmalloc of     new_ra, which might allow an attacker to cause a denial     of service (NULL pointer dereference and system crash).
    NOTE: this is disputed because new_ra is never used if     it is NULL.(CVE-2019-12381)An issue was discovered in     sunxi_divs_clk_setup in drivers/clk/sunxi/clk-sunxi.c     in the Linux kernel through 5.1.5. There is an     unchecked kstrndup of derived_name, which might allow     an attacker to cause a denial of service (NULL pointer     dereference and system crash). NOTE: This id is     disputed as not being an issue because 'The memory     allocation that was not checked is part of a code that     only runs at boot time, before user processes are     started. Therefore, there is no possibility for an     unprivileged user to control it, and no denial of     service.'.(CVE-2019-12455)An issue was discovered in     the MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel     through 5.1.5. It allows local users to cause a denial     of service or possibly have unspecified other impact by     changing the value of ioc_number between two kernel     reads of that value, aka a ''double fetch''     vulnerability. NOTE: a third party reports that this is     unexploitable because the doubly fetched value is not     used.(CVE-2019-12456)An issue was discovered in     get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in     the Linux kernel through 5.1.6. There is an unchecked     kstrdup_const of node_info-i1/4zvdev_port.name, which     might allow an attacker to cause a denial of service     (NULL pointer dereference and system     crash).(CVE-2019-12615)In parse_hid_report_descriptor     in drivers/input/tablet/gtco.c in the Linux kernel     through 5.2.1, a malicious USB device can send an HID     report that triggers an out-of-bounds write during     generation of debugging messages.(CVE-2019-13631)A     vulnerability was found in the Linux kernelaEURtms floppy     disk driver implementation. A local attacker with     access to the floppy device could call set_geometry in     drivers/block/floppy.c, which does not validate the     sect and head fields, causing an integer overflow and     out-of-bounds read. This flaw may crash the system or     allow an attacker to gather information causing     subsequent successful     attacks.(CVE-2019-14283)check_input_term in     sound/usb/mixer.c in the Linux kernel through 5.2.9     mishandles recursion, leading to kernel stack     exhaustion.(CVE-2019-15118)An issue was discovered in     the Linux kernel before 5.2.6. There is a     use-after-free caused by a malicious USB device in the     drivers/media/v4l2-core/v4l2-dev.c driver because     drivers/media/radio/radio-raremono.c does not properly     allocate memory.(CVE-2019-15211)An issue was discovered     in the Linux kernel before 5.0.10. There is a     use-after-free in the sound subsystem because card     disconnection causes certain data structures to be     deleted too early. This is related to sound/core/init.c     and sound/core/info.c.(CVE-2019-15214)An issue was     discovered in the Linux kernel before 5.1.8. There is a     NULL pointer dereference caused by a malicious USB     device in the drivers/media/usb/siano/smsusb.c     driver.(CVE-2019-15218)An issue was discovered in the     Linux kernel before 5.1.8. There is a NULL pointer     dereference caused by a malicious USB device in the     drivers/usb/misc/sisusbvga/sisusb.c     driver.(CVE-2019-15219)An issue was discovered in the     Linux kernel before 5.2.1. There is a use-after-free     caused by a malicious USB device in the     driverset/wireless/intersil/p54/p54usb.c     driver.(CVE-2019-15220)An issue was discovered in the     Linux kernel before 5.1.17. There is a NULL pointer     dereference caused by a malicious USB device in the     sound/usb/line6/pcm.c driver.(CVE-2019-15221)An issue     was discovered in the Linux kernel before 5.0.9. There     is a use-after-free in atalk_proc_exit, related to     net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and     net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)An     issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9.
    XFS partially wedges when a chgrp fails on account of     being out of disk quota. xfs_setattr_nonsize is failing     to unlock the ILOCK after the xfs_qm_vop_chown_reserve     call fails. This is primarily a local DoS attack     vector, but it might result as well in remote DoS if     the XFS filesystem is exported for instance via     NFS.(CVE-2019-15538)An issue was discovered in the     Linux kernel before 5.0.19. There is an out-of-bounds     array access in __xfrm_policy_unlink, which will cause     denial of service, because verify_newpolicy_info in     net/xfrm/xfrm_user.c mishandles directory     validation.(CVE-2019-15666)In the Linux kernel before     5.1.13, there is a memory leak in     drivers/scsi/libsas/sas_expander.c when SAS expander     discovery fails. This will cause a BUG and denial of     service.(CVE-2019-15807)An issue was discovered in the     Linux kernel before 5.0.5. There is a use-after-free     issue when hci_uart_register_dev() fails in     hci_uart_set_proto() in     drivers/bluetooth/hci_ldisc.c.(CVE-2019-15917)An issue     was discovered in the Linux kernel before 5.0.10.
    SMB2_write in fs/cifs/smb2pdu.c has a     use-after-free.(CVE-2019-15919)An issue was discovered     in the Linux kernel before 5.0.10. SMB2_read in     fs/cifs/smb2pdu.c has a use-after-free. NOTE: this was     not fixed correctly in 5.0.10 see the 5.0.11 ChangeLog,     which documents a memory leak.(CVE-2019-15920)An issue     was discovered in the Linux kernel before 5.0.4. The 9p     filesystem did not protect i_size_write() properly,     which causes an i_size_read() infinite loop and denial     of service on SMP systems.(CVE-2019-16413)An issue was     discovered in can_can_gw_rcv in net/can/gw.c in the     Linux kernel through 4.19.13. The CAN frame     modification rules allow bitwise logical operations     that can be also applied to the can_dlc field. Because     of a missing check, the CAN drivers may write arbitrary     content beyond the data registers in the CAN     controller's I/O memory when processing can-gw     manipulated outgoing frames. This is related to     cgw_csum_xor_rel. An unprivileged user can trigger a     system crash (general protection     fault).(CVE-2019-3701)A flaw was found in the Linux     kernel's Marvell wifi chip driver. A heap overflow in     mwifiex_update_bss_desc_with_ie function in     marvell/mwifiex/scan.c allows remote attackers to cause     a denial of service(system crash) or execute arbitrary     code.(CVE-2019-3846)A new software page cache side     channel attack scenario was discovered in operating     systems that implement the very common 'page cache'     caching mechanism. A malicious user/process could use     'in memory' page-cache knowledge to infer access     timings to shared memory and gain knowledge which can     be used to reduce effectiveness of cryptographic     strength by monitoring algorithmic behavior, infer     access patterns of memory to determine code paths     taken, and exfiltrate data to a blinded attacker     through page-granularity access times as a     side-channel.(CVE-2019-5489)In the Android kernel in     the video driver there is a kernel pointer leak due to     a WARN_ON statement. This could lead to local     information disclosure with System execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2019-9455)A vulnerability was found     in the arch/x86/lib/insn-eval.c function in the Linux     kernel. An attacker could corrupt the memory due to a     flaw in use-after-free access to an LDT entry caused by     a race condition between modify_ldt() and a #BR     exception for an MPX bounds violation.(CVE-2019-13233)

CVE-2019-10124: An issue was discovered in the hwpoison implementation in mm/memory-failure.c in the Linux kernel. When soft_offline_in_use_page() runs on a thp tail page after pmd is split, an attacker could cause a denial of service (bsc#1130699).

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel has multiple race conditions. (bsc#1133188)

CVE-2019-11811: An issue was discovered in the Linux kernel There was a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module was removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c. (bsc#1134397)

CVE-2019-11487: The Linux kernel allowed page reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It could occur with FUSE requests.
(bsc#1133190)

CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This used to affect nfc_llcp_build_gb in net/nfc/llcp_core.c. (bsc#1138293)

CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. (bsc#1135281)

CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bsc#1120843)

CVE-2018-7191: In the tun subsystem in the Linux kernel, dev_get_valid_name was not called before register_netdevice. This allowed local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. (bsc#1135603)

CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to obtain potentially sensitive information from kernel stack memory via a hidPCONNADD command, because a name field may not end with a '\0' character. (bsc#1134848)

CVE-2019-9500: An issue was discovered that lead to brcmfmac heap buffer overflow. (bsc#1132681)

CVE-2018-16880: A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, could trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may have lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (bsc#1122767)

CVE-2019-12819: The function __mdiobus_register() called put_device(), which triggered a fixed_mdio_bus_init use-after-free. This would cause a denial of service. (bsc#1138291)

CVE-2019-3882: A flaw was found in the Linux kernel's vfio interface implementation that permitted violation of the user's locked memory limit. If a device was bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may have caused a system memory exhaustion and thus a denial of service (DoS). (bsc#1131427)

CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bsc#1136424)

CVE-2019-8564: An issue was discoved which meant that brcmfmac frame validation could be bypassed. (bsc#1132673)

CVE-2019-9503: An issue was discoved which meant that brcmfmac frame validation could be bypassed. (bsc#1132828)

CVE-2019-9003: In the Linux kernel, attackers could trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a 'service ipmievd restart' loop. (bsc#1126704)

CVE-2017-5753: Systems with microprocessors utilizing speculative execution and branch prediction may have allowed unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection.

CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data.
Further, it would consume additional resources such as CPU and NIC processing power.

CVE-2018-16871: A NULL pointer dereference due to an anomalized NFS message sequence was fixed. (bnc#1137103).

CVE-2019-12614: An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c. There was an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash) (bnc#1137194).

CVE-2019-12817: On the PowerPC architecture, local attackers could access other users processes memory (bnc#1138263).

CVE-2018-20836: An issue was discovered in the Linux kernel There was a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free (bnc#1134395).

CVE-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses (bnc#1140575 1140577).

CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable because IP ID generation was changed to have a dependency on an address associated with a network namespace (bnc#1140577).

CVE-2019-11599: The coredump implementation in the Linux kernel did not use locking or other mechanisms to prevent vma layout or vma flags changes while it ran, which allowed local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c (bnc#1131645 1133738).

CVE-2019-13233: In arch/x86/lib/insn-eval.c in the Linux kernel, there was a use-after-free for access to an LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds violation (bnc#1140454).

CVE-2018-20855: An issue was discovered in the Linux kernel In create_qp_common in drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of stack memory to userspace(bsc#1143045).

CVE-2019-1125: Exclude ATOMs from speculation through SWAPGS (bsc#1139358).

CVE-2019-11810: An issue was discovered in the Linux kernel A NULL pointer dereference could occur when megasas_create_frame_pool() failed in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This caused a Denial of Service, related to a use-after-free (bnc#1134399).

CVE-2019-13631: In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel, a malicious USB device could send an HID report that triggered an out-of-bounds write during generation of debugging messages. (bnc#1142023)

CVE-2019-13648: In the Linux kernel on the powerpc platform, when hardware transactional memory was disabled, a local user could cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sent a crafted signal frame.
(bnc#1142254)

CVE-2019-14283: In the Linux kernel, set_geometry in drivers/block/floppy.c did not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It could be triggered by an unprivileged local user when a floppy disk was inserted. NOTE: QEMU creates the floppy device by default.
(bnc#1143191)

CVE-2019-14284: In the Linux kernel, drivers/block/floppy.c allows a denial of service by setup_format_params division-by-zero.
(bnc#1143189)

CVE-2019-12456: An issue was discovered in the MPT3COMMAND case in
_ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux. It allows local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a 'double fetch' vulnerability.
NOTE: a third-party reports that this is unexploitable because the doubly fetched value is not used. (bsc#1136922)

CVE-2019-12380: An issue was discovered in the efi subsystem in the Linux kernel phys_efi_set_virtual_address_map in arch/x86/platform/efi/efi.c and efi_call_phys_prolog in arch/x86/platform/efi/efi_64.c mishandle memory allocation failures.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc. Security Fix(es):A flaw was found in the     Linux kernel's NFS implementation, all versions 3.x and     all versions 4.x up to 4.20. An attacker, who is able     to mount an exported NFS filesystem, is able to trigger     a null pointer dereference by using an invalid NFS     sequence. This can panic the machine and deny access to     the NFS server. Any outstanding disk writes to the NFS     server will be lost.(CVE-2018-16871)An issue was     discovered in the Linux kernel before 4.18.7. In     create_qp_common in drivers/infiniband/hw/mlx5/qp.c,     mlx5_ib_create_qp_resp was never initialized, resulting     in a leak of stack memory to     userspace.(CVE-2018-20855)An issue was discovered in     the Linux kernel before 4.18.7. In block/blk-core.c,     there is an __blk_drain_queue() use-after-free because     a certain error case is mishandled.(CVE-2018-20856)The     Linux kernel 4.x (starting from 4.1) and 5.x before     5.0.8 allows Information Exposure (partial kernel     address disclosure), leading to a KASLR bypass.
    Specifically, it is possible to extract the KASLR     kernel image offset using the IP ID values the kernel     produces for connection-less protocols (e.g., UDP and     ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). This     key contains enough bits from a kernel address (of a     static variable) so when the key is extracted (via     enumeration), the offset of the kernel image is     exposed. This attack can be carried out remotely, by     the attacker forcing the target device to send UDP or     ICMP (or certain other) traffic to attacker-controlled     IP addresses. Forcing a server to send UDP traffic is     trivial if the server is a DNS server. ICMP traffic is     trivial if the server answers ICMP Echo requests     (ping). For client targets, if the target visits the     attacker's web page, then WebRTC or gQUIC can be used     to force UDP traffic to attacker-controlled IP     addresses. NOTE: this attack against KASLR became     viable in 4.1 because IP ID generation was changed to     have a dependency on an address associated with a     network namespace.(CVE-2019-10639)** DISPUTED ** An     issue was discovered in ip6_ra_control in     net/ipv6/ipv6_sockglue.c in the Linux kernel through     5.1.5.

NOTE: this is disputed     because new_ra is never used if it is     NULL.(CVE-2019-12381)** DISPUTED ** An issue was     discovered in the MPT3COMMAND case in _ctl_ioctl_main     in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux     kernel through 5.1.5. It allows local users to cause a     denial of service or possibly have unspecified other     impact by changing the value of ioc_number between two     kernel reads of that value, aka a 'double fetch'     vulnerability. NOTE: a third party reports that this is     unexploitable because the doubly fetched value is not     used.(CVE-2019-12456)An issue was discovered in the     Linux kernel before 4.20.15. The nfc_llcp_build_tlv     function in netfc/llcp_commands.c may return NULL. If     the caller does not check for this, it will trigger a     NULL pointer dereference. This will cause denial of     service. This affects nfc_llcp_build_gb in     netfc/llcp_core.c.(CVE-2019-12818)An issue was     discovered in the Linux kernel before 5.0. The function
    __mdiobus_register() in driverset/phy/mdio_bus.c calls     put_device(), which will trigger a fixed_mdio_bus_init     use-after-free. This will cause a denial of     service.(CVE-2019-12819)A NULL pointer dereference     vulnerability in the function     nfc_genl_deactivate_target() in netfcetlink.c in the     Linux kernel before 5.1.13 can be triggered by a     malicious user-mode program that omits certain NFC     attributes, leading to denial of     service.(CVE-2019-12984)In the Linux kernel before     5.1.17, ptrace_link in kernel/ptrace.c mishandles the     recording of the credentials of a process that wants to     create a ptrace relationship, which allows local users     to obtain root access by leveraging certain scenarios     with a parent-child process relationship, where a     parent drops privileges and calls execve (potentially     allowing control by an attacker). One contributing     factor is an object lifetime issue (which can also     cause a panic). Another contributing factor is     incorrect marking of a ptrace relationship as     privileged, which is exploitable through (for example)     Polkit's pkexec helper with PTRACE_TRACEME. NOTE:
    SELinux deny_ptrace might be a usable workaround in     some environments.(CVE-2019-13272)In     parse_hid_report_descriptor in     drivers/input/tablet/gtco.c in the Linux kernel through     5.2.1, a malicious USB device can send an HID report     that triggers an out-of-bounds write during generation     of debugging messages.(CVE-2019-13631)In the Linux     kernel through 5.2.1 on the powerpc platform, when     hardware transactional memory is disabled, a local user     can cause a denial of service (TM Bad Thing exception     and system crash) via a sigreturn() system call that     sends a crafted signal frame. This affects     arch/powerpc/kernel/signal_32.c and     arch/powerpc/kernel/signal_64.c.(CVE-2019-13648)In the     Linux kernel before 5.2.3, set_geometry in     drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and     out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been     inserted. NOTE: QEMU creates the floppy device by     default.(CVE-2019-14283)In the Linux kernel before     5.2.3, drivers/block/floppy.c allows a denial of     service by setup_format_params division-by-zero. Two     consecutive ioctls can trigger the bug: the first one     should set the drive geometry with .sect and .rate     values that make F_SECT_PER_TRACK be zero. Next, the     floppy format operation should be called. It can be     triggered by an unprivileged local user even when a     floppy disk has not been inserted. NOTE: QEMU creates     the floppy device by default.(CVE-2019-14284)In the     Linux kernel before 4.16.4, a double-locking error in     drivers/usb/dwc3/gadget.c may potentially cause a     deadlock with f_hid.(CVE-2019-14763)An issue was     discovered in the Linux kernel before 5.2.6. There is a     use-after-free caused by a malicious USB device in the     drivers/media/v4l2-core/v4l2-dev.c driver because     drivers/media/radio/radio-raremono.c does not properly     allocate memory.(CVE-2019-15211)An issue was discovered     in the Linux kernel before 5.0.9. There is a     use-after-free in atalk_proc_exit, related to     net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and     net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)A flaw     was found in the way the sit_init_net function in the     Linux kernel handled resource cleanup on errors. This     flaw allows an attacker to use the error conditions to     crash the system.(CVE-2019-16994)Note:
    kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions     in EulerOS Virtualization for ARM 64 3.0.2.0 return     incorrect time information when executing the uname -a     command.

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-5390 aka 'SegmentSmack': A remote attacker even with relatively low bandwidth could have caused lots of CPU usage by triggering the worst case scenario during IP and/or TCP fragment reassembly (bsc#1102340)

CVE-2018-7191: In the tun subsystem in the Linux kernel, dev_get_valid_name was not called before register_netdevice. This allowed local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. (bnc#1135603)

CVE-2018-20836: A race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, could have lead to a use-after-free. (bnc#1134395)

CVE-2019-12614: An unchecked kstrdup might have allowed an attacker to cause denial of service (a NULL pointer dereference and system crash).
(bnc#1137194)

CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may have returned NULL. If the caller did not check for this, it would trigger a NULL pointer dereference. This would cause denial of service. (bnc#1138293)

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main() allowed local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a 'double fetch' vulnerability.
(bsc#1136922)

CVE-2019-11487: An attacker could have triggered use-after-free via page reference count overflow on slow filesystems with at least of 140 GiB of RAM available. (bnc#1133190)

The SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols.
When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575]

CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass.
Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server.
ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. [bnc#1140577]

CVE-2018-20836: A race condition used to exist in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. [bnc#1134395]

CVE-2019-10126: A heap-based buffer overflow in the wireless driver code was fixed. This issue might have lead to memory corruption and possibly other consequences. [bnc#1136935]

CVE-2019-11599: The coredump implementation did not use locking or other mechanisms to prevent vma layout or vma flags changes while it ran, which allowed local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.
[bnc#1131645].

CVE-2019-12614: There was an unchecked kstrdup of prop->name on PowerPC platforms, which allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). [bnc#1137194]

CVE-2018-16871: A flaw was found in the NFS implementation. An attacker who was able to mount an exported NFS filesystem was able to trigger a NULL pointer dereference by an invalid NFS sequence. This could panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will were lost.
[bnc#1137103]

CVE-2019-12819: The function __mdiobus_register() used to call put_device(), which would trigger a fixed_mdio_bus_init use-after-free error. This would cause a denial of service. [bnc#1138291]

CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller did not check for this, it could trigger a NULL pointer dereference. This would cause denial of service. [bnc#1138293]

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main() allowed local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a 'double fetch' vulnerability.
[bsc#1136922]

CVE-2019-12380: An issue was in the EFI subsystem existed that mishandled memory allocation failures. Note, however, that all relevant code runs only at boot-time, before any user processes are started. Therefore, there was no possibility for an unprivileged user to exploit this issue. [bnc#1136598]

  - CVE-2019-12819: The function __mdiobus_register() in     drivers/net/phy/mdio_bus.c calls put_device(), which     will trigger a fixed_mdio_bus_init use-after-free. This     will cause a denial of service (bnc#1138291).

  - CVE-2019-12818: The nfc_llcp_build_tlv function in     net/nfc/llcp_commands.c may return NULL. If the caller     did not check for this, it will trigger a NULL pointer     dereference. This will cause denial of service. This     affects nfc_llcp_build_gb in net/nfc/llcp_core.c     (bnc#1138293).

  - CVE-2019-12456: An issue was discovered in the     MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c that allowed local     users to cause a denial of service or possibly have     unspecified other impact by changing the value of     ioc_number between two kernel reads of that value, aka a     'double fetch' vulnerability. (bnc#1136922)

  - CVE-2019-12380: An issue was discovered in the efi     subsystem in the Linux kernel     phys_efi_set_virtual_address_map in     arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory     allocation failures (bnc#1136598).

  - CVE-2019-3846: A flaw that allowed an attacker to     corrupt memory and possibly escalate privileges was     found in the mwifiex kernel module while connecting to a     malicious wireless network (bnc#1136424).

  - CVE-2019-10124: An attacker could exploit an issue in     the hwpoison implementation to cause a denial of service     (BUG). (bsc#1130699)

  - CVE-2019-12382: In the drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c was an unchecked kstrdup     of fwstr, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash) (bnc#1136586).

  - CVE-2019-11487: The Linux kernel allowed page->_refcount     reference count overflow, with resultant use-after-free     issues, if about 140 GiB of RAM exists. This is related     to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h,     kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests (bnc#1133190).
