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.

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2104 advisory.

  - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an     out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)

  - An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c. (CVE-2017-18595)

  - 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 an unchecked kstrdup of prop->name, which might allow an attacker to cause     a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)

  - 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)

  - In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and     unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list     in fs/ext4/super.c. (CVE-2019-19447)

  - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - In the Android kernel in i2c driver there is a possible out of bounds write due to memory corruption. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9454)

  - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)

  - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to     a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it,     aka CID-2e90ca68b0d2. (CVE-2020-9383)

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

  - In the tun subsystem in the Linux kernel before     4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows 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. This is similar to     CVE-2013-4343.(CVE-2018-7191)

  - A memory leak in the crypto_report() function in     crypto/crypto_user_base.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service     (memory consumption) by triggering crypto_report_alg()     failures, aka CID-ffdde5932042.(CVE-2019-19062)

  - An issue was discovered in net/ipv4/sysctl_net_ipv4.c     in the Linux kernel before 5.0.11. 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/sys/net/ipv4/tcp_min_rtt_wlen, leading     to a denial of service or possibly unspecified other     impact, aka CID-19fad20d15a6.(CVE-2019-18805)

  - In the Linux kernel before 5.0, a memory leak exists in     sit_init_net() in net/ipv6/sit.c when register_netdev()     fails to register sitn->fb_tunnel_dev, which may cause     denial of service, aka     CID-07f12b26e21a.(CVE-2019-16994)

  - An issue was discovered in the Linux kernel before     5.0.6. There is a memory leak issue when idr_alloc()     fails in genl_register_family() in     net/netlink/genetlink.c.(CVE-2019-15921)

  - 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 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 out-of-bounds access issue was found in the Linux     kernel, all versions through 5.3, in the way Linux     kernel's KVM hypervisor implements the Coalesced MMIO     write operation. It operates on an MMIO ring buffer     'struct kvm_coalesced_mmio' object, wherein write     indices 'ring->first' and 'ring->last' value could be     supplied by a host user-space process. An unprivileged     host user or process with access to '/dev/kvm' device     could use this flaw to crash the host kernel, resulting     in a denial of service or potentially escalating     privileges on the system.(CVE-2019-14821)

  - ** DISPUTED ** 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)

  - ** DISPUTED ** 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 fs/xfs/xfs_super.c in the     Linux kernel before 4.18. A use after free exists,     related to xfs_fs_fill_super failure.(CVE-2018-20976)

  - 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)

  - A flaw was found in the Linux kernel's NFS41+     subsystem. NFS41+ shares mounted in different network     namespaces at the same time can make bc_svc_process()     use wrong back-channel IDs and cause a use-after-free     vulnerability. Thus a malicious container user can     cause a host kernel memory corruption and a system     panic. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out.(CVE-2018-16884)

  - 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 found in the Linux kernel ipv6     implementation of GRE tunnels which allows a remote     attacker to trigger an out-of-bounds access. At this     time we understand no trust barrier has been crossed     and there is no security implications in this     flaw.(CVE-2017-5897)

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the kernel packages installed, the EulerOS 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):Heap-based buffer overflow     in the udf_load_logicalvol function in fs/udf/super.c     in the Linux kernel before 3.4.5 allows remote     attackers to cause a denial of service (system crash)     or possibly have unspecified other impact via a crafted     UDF filesystem.(CVE-2012-3400)The     mmc_ioctl_cdrom_read_data function in     drivers/cdrom/cdrom.c in the Linux kernel through 3.10     allows local users to obtain sensitive information from     kernel memory via a read operation on a malfunctioning     CD-ROM drive.(CVE-2013-2164)The     sctp_sf_do_5_2_4_dupcook function in     net/sctp/sm_statefuns.c in the SCTP implementation in     the Linux kernel before 3.8.5 does not properly handle     associations during the processing of a duplicate     COOKIE ECHO chunk, which allows remote attackers to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unspecified other impact     via crafted SCTP traffic.(CVE-2013-2206)The (1)     get_user and (2) put_user API functions in the Linux     kernel before 3.5.5 on the v6k and v7 ARM platforms do     not validate certain addresses, which allows attackers     to read or modify the contents of arbitrary kernel     memory locations via a crafted application, as     exploited in the wild against Android devices in     October and November 2013.(CVE-2013-6282)An issue was     discovered in the Linux kernel before 4.20. There is a     race condition in smp_task_timedout() and     smp_task_done() in drivers/scsi/libsas/sas_expander.c,     leading to a use-after-free.(CVE-2018-20836)The Siemens     R3964 line discipline driver in drivers/tty/n_r3964.c     in the Linux kernel before 5.0.8 has multiple race     conditions.(CVE-2019-11486)The Linux kernel before     5.1-rc5 allows 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.(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. There is a race     condition leading to a use-after-free, related to net     namespace cleanup.(CVE-2019-11815)A flaw was found in     the Linux kernel in the function     hid_debug_events_read() in drivers/hid/hid-debug.c file     which may enter an infinite loop with certain     parameters passed from a userspace. A local privileged     user ('root') can cause a system lock up and a denial     of service. 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 an unchecked kstrdup of     prop-i1/4zname, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash).(CVE-2019-12614)An issue was discovered in     net/ipv4/sysctl_net_ipv4.c in the Linux kernel before     5.0.11. 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.

    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.

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)

According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :

  - [3.10.0-862.9.1.vz7.63.3 to 3.10.0-1062.4.2.vz7.116.7]     xfs: potential denial of service caused by missing     unlock operation in xfs_setattr_nonsize(). It was     discovered that xfs_setattr_nonsize() would not unlock     'ILOCK' lock if the user or group were out of their     disk quota. As a result, any subsequent operation,     which needed to take 'ILOCK', would get stuck, leading     to a denial of service.

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream 'x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()' commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped.(CVE-2019-15902)

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)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

This updated advisory text mentions the additional non-security changes and notes the need to install new binary packages.

CVE-2019-0136

It was discovered that the wifi soft-MAC implementation (mac80211) did not properly authenticate Tunneled Direct Link Setup (TDLS) messages.
A nearby attacker could use this for denial of service (loss of wifi connectivity).

CVE-2019-9506

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered a weakness in the Bluetooth pairing protocols, dubbed the 'KNOB attack'. An attacker that is nearby during pairing could use this to weaken the encryption used between the paired devices, and then to eavesdrop on and/or spoof communication between them.

This update mitigates the attack by requiring a minimum encryption key length of 56 bits.

CVE-2019-11487

Jann Horn discovered that the FUSE (Filesystem-in-Userspace) facility could be used to cause integer overflow in page reference counts, leading to a use-after-free. On a system with sufficient physical memory, a local user permitted to create arbitrary FUSE mounts could use this for privilege escalation.

By default, unprivileged users can only mount FUSE filesystems through fusermount, which limits the number of mounts created and should completely mitigate the issue.

CVE-2019-15211

The syzkaller tool found a bug in the radio-raremono driver that could lead to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15212

The syzkaller tool found that the rio500 driver does not work correctly if more than one device is bound to it. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15215

The syzkaller tool found a bug in the cpia2_usb driver that leads to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15216

The syzkaller tool found a bug in the yurex driver that leads to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15218

The syzkaller tool found that the smsusb driver did not validate that USB devices have the expected endpoints, potentially leading to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15219

The syzkaller tool found that a device initialisation error in the sisusbvga driver could lead to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15220

The syzkaller tool found a race condition in the p54usb driver which could lead to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15221

The syzkaller tool found that the line6 driver did not validate USB devices' maximum packet sizes, which could lead to a heap buffer overrun. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15292

The Hulk Robot tool found missing error checks in the Appletalk protocol implementation, which could lead to a use-after-free. The security impact of this is unclear.

CVE-2019-15538

Benjamin Moody reported that operations on XFS hung after a chgrp command failed due to a disk quota. A local user on a system using XFS and disk quotas could use this for denial of service.

CVE-2019-15666

The Hulk Robot tool found an incorrect range check in the network transformation (xfrm) layer, leading to out-of-bounds memory accesses.
A local user with CAP_NET_ADMIN capability (in any user namespace) could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15807

Jian Luo reported that the Serial Attached SCSI library (libsas) did not correctly handle failure to discover devices beyond a SAS expander. This could lead to a resource leak and crash (BUG). The security impact of this is unclear.

CVE-2019-15924

The Hulk Robot tool found a missing error check in the fm10k Ethernet driver, which could lead to a NULL pointer dereference and crash (BUG/oops). The security impact of this is unclear.

CVE-2019-15926

It was found that the ath6kl wifi driver did not consistently validate traffic class numbers in received control packets, leading to out-of-bounds memory accesses. A nearby attacker on the same wifi network could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

For Debian 8 'Jessie', these problems have been fixed in version 4.9.189-3. This version also includes a fix for Debian bug #930904, and other fixes included in upstream stable updates.

We recommend that you upgrade your linux-4.9 and linux-latest-4.9 packages. You will need to use 'apt-get upgrade --with-new-pkgs' or 'apt upgrade' as the binary package names have changed.
