The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: out of bounds read in drivers/media/usb/dvb-usb/technisat-usb2.c (CVE-2019-15505)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during     authorization of SCSI commands, which allows local users to bypass intended access restrictions via an     SG_IO ioctl call that leverages overlapping opcodes. (CVE-2012-4542)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has kernel packages installed that are affected by multiple vulnerabilities:

  - In the Linux kernel through 4.19.6, a local user could exploit a use-after-free in the ALSA driver by     supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in     sound/usb/card.c. (CVE-2018-19824)

  - 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 4.20.2. An out-of-bounds access exists in the function     build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)

This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An     attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations     before the required authentication process has completed. This could lead to different denial-of-service     scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already     existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge     Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)

  - In create_pinctrl of core.c, there is a possible out of bounds read due to a use after free. This could     lead to local information disclosure with no additional execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-140550171     (CVE-2020-0427)

  - A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)

  - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could     overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in     ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.
    (CVE-2020-25211)

  - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption     and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause     the system to crash or cause a denial of service. The highest threat from this vulnerability is to data     confidentiality and integrity as well as system availability. (CVE-2020-25643)

  - A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may     be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE     tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from     this vulnerability is to data confidentiality. (CVE-2020-25645)

  - A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw     allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that     relies on UDP source port randomization are indirectly affected as well on the Linux Based Products     (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4,     SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE     W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All     versions, SIMATIC NET CP 1243-1 (incl. SIPLUS variants): Versions 3.1.39 and later, SIMATIC NET CP 1243-7     LTE EU: Version (CVE-2020-25705)

  - A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.
    drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.
    (CVE-2020-29661)

  - A flaw was found in the way memory resources were freed in the unix_stream_recvmsg function in the Linux     kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by     exhausting available memory. The highest threat from this vulnerability is to system availability.
    (CVE-2021-20265)

  - An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI     subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the     pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)

  - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)

  - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a     Netlink message. (CVE-2021-27365)

  - An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.
    (CVE-2021-3347)

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14218-1 advisory.

  - An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket     option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general     protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be     triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after     namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of     the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before     4.9.187. (CVE-2017-18509)

  - 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)

  - Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to potentially enable denial of service of the host system via     local access. (CVE-2018-12207)

  - 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)

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated     user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135)

  - 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)

  - A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost     functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A     privileged guest user able to pass descriptors with invalid length to the host when migration is underway,     could use this flaw to increase their privileges on the host. (CVE-2019-14835)

  - 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 5.1.8. There is a double-free caused by a malicious USB     device in the drivers/usb/misc/rio500.c driver. (CVE-2019-15212)

  - An issue was discovered in the Linux kernel before 5.0.14. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/usb/misc/yurex.c driver. (CVE-2019-15216)

  - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)

  - 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 through 5.2.9. There is a NULL pointer dereference caused by a     malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver.
    (CVE-2019-15291)

  - 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)

  - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via     crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)

  - 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)

  - 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 the Linux kernel before 4.20.2. An out-of-bounds access exists in the function     build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)

  - drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16232)

  - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16233)

  - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16234)

  - 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)

  - ax25_create in net/ax25/af_ax25.c in the AF_AX25 network module in the Linux kernel 3.16 through 5.3.2     does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-0614e2b73768. (CVE-2019-17052)

  - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel     through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket,     aka CID-e69dbd4619e7. (CVE-2019-17053)

  - atalk_create in net/appletalk/ddp.c in the AF_APPLETALK network module in the Linux kernel through 5.3.2     does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-6cc03e8aa36c. (CVE-2019-17054)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21. (CVE-2019-17055)

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - In the Android kernel in Pixel C USB monitor driver there is a possible OOB write due to a missing bounds     check. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation. (CVE-2019-9456)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

The Linux Kernel kvm hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port failed to add a port, which may have caused denial of service (bsc#1152685).

CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150457).

CVE-2019-10220: Added sanity checks on the pathnames passed to the user space. (bsc#1144903).

CVE-2019-17055: The AF_ISDN network module in the Linux kernel did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bnc#1152782).

CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bsc#1152788).

CVE-2019-16413: The 9p filesystem did not protect i_size_write() properly, which caused an i_size_read() infinite loop and denial of service on SMP systems (bnc#1151347).

CVE-2019-15902: A backporting issue was discovered that re-introduced the Spectre vulnerability it had aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).

CVE-2019-15291: Fixed a NULL pointer dereference issue that could be caused by a malicious USB device (bnc#1146519).

CVE-2019-15807: Fixed a memory leak in the SCSI module that could be abused to cause denial of service (bnc#1148938).

CVE-2019-13272: Fixed a mishandled the recording of the credentials of a process that wants to create a ptrace relationship, which allowed 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).
(bnc#1140671).

CVE-2019-14821: An out-of-bounds access issue was fixed in the kernel's kvm hypervisor. 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 (bnc#1151350).

CVE-2019-15505: An out-of-bounds issue had been fixed that could be caused by crafted USB device traffic (bnc#1147122).

CVE-2017-18595: A double free in allocate_trace_buffer was fixed (bnc#1149555).

CVE-2019-14835: A buffer overflow flaw was found in the kernel's vhost functionality that translates virtqueue buffers to IOVs. A privileged guest user able to pass descriptors with invalid length to the host could use this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-15216: A NULL pointer dereference was fixed that could be malicious USB device (bnc#1146361).

CVE-2019-15924: A a NULL pointer dereference has been fixed in the drivers/net/ethernet/intel/fm10k module (bnc#1149612).

CVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific socket option, an attacker could control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)

CVE-2019-9506: The Bluetooth BR/EDR specification used to permit sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and inject arbitrary ciphertext without the victim noticing (bnc#1137865).

CVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath was fixed (bnc#1146378).

A use after free exists, related to     xfs_fs_fill_super failure.(CVE-2018-20976)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)A vulnerability was found in     Linux kernel's, versions up to 3.10, implementation of     overlayfs. An attacker with local access can create a     denial of service situation via NULL pointer     dereference in ovl_posix_acl_create function in     fs/overlayfs/dir.c. This can allow attackers with     ability to create directories on overlayfs to crash the     kernel creating a denial of service     (DOS).(CVE-2019-10140)In the Linux kernel, a certain     net/ipv4/tcp_output.c change, which was properly     incorporated into 4.16.12, was incorrectly backported     to the earlier longterm kernels, introducing a new     vulnerability that was potentially more severe than the     issue that was intended to be fixed by backporting.
    Specifically, by adding to a write queue between     disconnection and re-connection, a local attacker can     trigger multiple use-after-free conditions. This can     result in a kernel crash, or potentially in privilege     escalation.(CVE-2019-15239)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)drivers     et/wireless/ath/ath10k/usb.c in the Linux kernel     through 5.2.8 has a NULL pointer dereference via an     incomplete address in an endpoint     descriptor.(CVE-2019-15099)drivers     et/wireless/ath/ath6kl/usb.c in the Linux kernel     through 5.2.9 has a NULL pointer dereference via an     incomplete address in an endpoint     descriptor.(CVE-2019-15098)A flaw was found in the     Linux kernel's Bluetooth implementation of UART.

An attacker can use this flaw to     crash the system, corrupt memory, or create other     adverse security     affects.(CVE-2019-10142)drivers/media/usb/dvb-usb/techn     isat-usb2.c in the Linux kernel through 5.2.9 has an     out-of-bounds read via crafted USB device traffic     (which may be remote via usbip or     usbredir).(CVE-2019-15505)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     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)A buffer     overflow flaw was found, in versions from 2.6.34 to     5.2.x, in the way Linux kernel's vhost functionality     that translates virtqueue buffers to IOVs, logged the     buffer descriptors during migration. A privileged guest     user able to pass descriptors with invalid length to     the host when migration is underway, could use this     flaw to increase their privileges on the     host.(CVE-2019-14835)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)An     information disclosure vulnerability exists when     certain central processing units (CPU) speculatively     access memory, aka 'Windows Kernel Information     Disclosure Vulnerability'.
    (CVE-2019-1125)drivers/scsi/qla2xxx/qla_os.c in the     Linux kernel 5.2.14 does not check the alloc_workqueue     return value, leading to a NULL pointer     dereference.(CVE-2019-16233)An issue was discovered in     the Linux kernel before 5.0.11. fm10k_init_module in     drivers et/ethernet/intel/fm10k/fm10k_main.c has a NULL     pointer dereference because there is no -ENOMEM upon an     alloc_workqueue failure.(CVE-2019-15924)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     drivers et/wireless/intersil/p54/p54usb.c     driver.(CVE-2019-15220 )In the Linux kernel before     5.1.7, a device can 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 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). An attack may be conducted by hosting a     crafted web page that uses WebRTC or gQUIC to force UDP     traffic to attacker-controlled IP     addresses.(CVE-2019-10638)There is heap-based buffer     overflow in Linux kernel, all versions up to, excluding     5.3, in the marvell wifi chip driver in Linux kernel,     that allows local users to cause a denial of     service(system crash) or possibly execute arbitrary     code.( CVE-2019-14814)** RESERVED ** This candidate has     been reserved by an organization or individual that     will use it when announcing a new security problem.
    When the candidate has been publicized, the details for     this candidate will be provided.( CVE-2019-14815)There     is heap-based buffer overflow in kernel, all versions     up to, excluding 5.3, in the marvell wifi chip driver     in Linux kernel, that allows local users to cause a     denial of service(system crash) or possibly execute     arbitrary code.( CVE-2019-14816)A flaw was found in the     way Linux kernel KVM hypervisor emulated instructions     such as sgdt/sidt/fxsave/fxrstor. It did not check     current privilege(CPL) level while emulating     unprivileged instructions. An unprivileged guest     user/process could use this flaw to potentially     escalate privileges inside guest.(CVE-2018-10853)A NULL     pointer dereference was found in the net/rds/rdma.c
    __rds_rdma_map() function in the Linux kernel before     4.14.7 allowing local attackers to cause a system panic     and a denial-of-service, related to RDS_GET_MR and     RDS_GET_MR_FOR_DEST.(CVE-2018-7492)An issue was     discovered in the Linux kernel before 4.20.15. The     nfc_llcp_build_tlv function in net fc/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 5.1.8. 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 15 SP1 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-14835: A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could have used this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).

CVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).

CVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).

CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE was misused in arch/powerpc/kernel/process.c (bnc#1149713).

CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).

CVE-2019-15920: SMB2_read in fs/cifs/smb2pdu.c had a use-after-free.
(bnc#1149626).

CVE-2019-15921: There was a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c (bnc#1149602).

CVE-2018-21008: A use-after-free could have been caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).

CVE-2019-15919: SMB2_write in fs/cifs/smb2pdu.c had a use-after-free (bnc#1149552).

CVE-2019-15926: An out-of-bounds access existed in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c (bnc#1149527).

CVE-2019-15927: An out-of-bounds access existed in the function build_audio_procunit in the file sound/usb/mixer.c (bnc#1149522).

CVE-2019-15902: 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 (bnc#1149376).

CVE-2019-15666: There was 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 mishandled directory validation (bnc#1148394).

CVE-2019-15219: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver (bnc#1146524).

The SUSE Linux Enterprise 12 SP4 for Azure kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-15291: There was a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540).

CVE-2019-14821: An out-of-bounds access issue was found 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 (bnc#1151350).

CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).

CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation.
This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).

CVE-2019-14835: A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could have used this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).

CVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).

CVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).

CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE was misused in arch/powerpc/kernel/process.c (bnc#1149713).

CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).

CVE-2019-15920: SMB2_read in fs/cifs/smb2pdu.c had a use-after-free.
(bnc#1149626).

CVE-2019-15921: There was a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c (bnc#1149602).

CVE-2019-15926: An out-of-bounds access existed in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c (bnc#1149527).

CVE-2019-15927: An out-of-bounds access existed in the function build_audio_procunit in the file sound/usb/mixer.c (bnc#1149522).

CVE-2019-15902: 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 (bnc#1149376).

CVE-2019-15666: There was 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 mishandled directory validation (bnc#1148394).
