"An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es) :

* It was found that the Linux kernel's IPv6 implementation mishandled
socket options. A local attacker could abuse concurrent access to the
socket options to escalate their privileges, or cause a denial of
service (use-after-free and system crash) via a crafted sendmsg system
call. (CVE-2016-3841, Important)

* Several Moderate and Low impact security issues were found in the
Linux kernel. Space precludes documenting each of these issues in this
advisory. Refer to the CVE links in the References section for a
description of each of these vulnerabilities. (CVE-2013-4312,
CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844,

"The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.69 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2015-8962: Double free vulnerability in the
    sg_common_write function in drivers/scsi/sg.c in the
    Linux kernel allowed local users to gain privileges or
    cause a denial of service (memory corruption and system
    crash) by detaching a device during an SG_IO ioctl call
    (bnc#1010501).

  - CVE-2015-8963: Race condition in kernel/events/core.c in
    the Linux kernel allowed local users to gain privileges
    or cause a denial of service (use-after-free) by
    leveraging incorrect handling of an swevent data
    structure during a CPU unplug operation (bnc#1010502).

  - CVE-2015-8964: The tty_set_termios_ldisc function in
    drivers/tty/tty_ldisc.c in the Linux kernel allowed
    local users to obtain sensitive information from kernel
    memory by reading a tty data structure (bnc#1010507).

  - CVE-2016-10088: The sg implementation in the Linux
    kernel did not properly restrict write operations in
    situations where the KERNEL_DS option is set, which
    allowed local users to read or write to arbitrary kernel
    memory locations or cause a denial of service
    (use-after-free) by leveraging access to a /dev/sg
    device, related to block/bsg.c and drivers/scsi/sg.c.
    NOTE: this vulnerability exists because of an incomplete
    fix for CVE-2016-9576 (bnc#1017710).

  - CVE-2016-7910: Use-after-free vulnerability in the
    disk_seqf_stop function in block/genhd.c in the Linux
    kernel allowed local users to gain privileges by
    leveraging the execution of a certain stop operation
    even if the corresponding start operation had failed
    (bnc#1010716).

  - CVE-2016-7911: Race condition in the get_task_ioprio
    function in block/ioprio.c in the Linux kernel allowed
    local users to gain privileges or cause a denial of
    service (use-after-free) via a crafted ioprio_get system
    call (bnc#1010711).

  - CVE-2016-7913: The xc2028_set_config function in
    drivers/media/tuners/tuner-xc2028.c in the Linux kernel
    allowed local users to gain privileges or cause a denial
    of service (use-after-free) via vectors involving
    omission of the firmware name from a certain data
    structure (bnc#1010478).

  - CVE-2016-7914: The assoc_array_insert_into_terminal_node
    function in lib/assoc_array.c in the Linux kernel did
    not check whether a slot is a leaf, which allowed local
    users to obtain sensitive information from kernel memory
    or cause a denial of service (invalid pointer
    dereference and out-of-bounds read) via an application
    that uses associative-array data structures, as
    demonstrated by the keyutils test suite (bnc#1010475).

  - CVE-2016-8399: An elevation of privilege vulnerability
    in the kernel networking subsystem could enable a local
    malicious application to execute arbitrary code within
    the context of the kernel. This issue is rated as
    Moderate because it first requires compromising a
    privileged process and current compiler optimizations
    restrict access to the vulnerable code. Product:
    Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:
    A-31349935 (bnc#1014746).

  - CVE-2016-8633: drivers/firewire/net.c in the Linux
    kernel, in certain unusual hardware configurations,
    allowed remote attackers to execute arbitrary code via
    crafted fragmented packets (bnc#1008833).

  - CVE-2016-8645: The TCP stack in the Linux kernel
    mishandled skb truncation, which allowed local users to
    cause a denial of service (system crash) via a crafted
    application that made sendto system calls, related to
    net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c
    (bnc#1009969).

  - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux
    kernel allowed local users to bypass integer overflow
    checks, and cause a denial of service (memory
    corruption) or have unspecified other impact, by
    leveraging access to a vfio PCI device file for a
    VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine
    confusion bug' (bnc#1007197).

  - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the
    Linux kernel misuses the kzalloc function, which allowed
    local users to cause a denial of service (integer
    overflow) or have unspecified other impact by leveraging
    access to a vfio PCI device file (bnc#1007197).

  - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux
    kernel did not properly initialize Code Segment (CS) in
    certain error cases, which allowed local users to obtain
    sensitive information from kernel stack memory via a
    crafted application (bnc#1013038).

  - CVE-2016-9793: The sock_setsockopt function in
    net/core/sock.c in the Linux kernel mishandled negative
    values of sk_sndbuf and sk_rcvbuf, which allowed local
    users to cause a denial of service (memory corruption
    and system crash) or possibly have unspecified other
    impact by leveraging the CAP_NET_ADMIN capability for a
    crafted setsockopt system call with the (1)
    SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531
    1013542).

  - CVE-2016-9806: Race condition in the netlink_dump
    function in net/netlink/af_netlink.c in the Linux kernel
    allowed local users to cause a denial of service (double
    free) or possibly have unspecified other impact via a
    crafted application that made sendmsg system calls,
    leading to a free operation associated with a new dump
    that started earlier than anticipated (bnc#1013540
    1017589).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux
    kernel allowed local users to obtain sensitive
    information from kernel memory or cause a denial of
    service (use-after-free) via a crafted application that
    leverages instruction emulation for fxrstor, fxsave,
    sgdt, and sidt (bsc#1019851).

  - CVE-2017-2583: Fixed broken emulation of 'MOV SS, null
    selector' (bsc#1020602).

  - CVE-2017-5551: Clear SGID bit when setting file
    permissions on tmpfs (bsc#1021258).

"It was discovered that an out of bounds read vulnerability existed in
the associative array implementation in the Linux kernel. A local
attacker could use this to cause a denial of service (system crash) or
expose sensitive information. (CVE-2016-7914)

It was discovered that a NULL pointer dereference existed in the
Direct Rendering Manager (DRM) driver for VMware devices in the Linux
kernel. A local attacker could use this to cause a denial of service
(system crash). (CVE-2017-7261)

It was discovered that the USB Cypress HID drivers for the Linux
kernel did not properly validate reported information from the device.
An attacker with physical access could use this to expose sensitive
information (kernel memory). (CVE-2017-7273)

A reference count bug was discovered in the Linux kernel ipx protocol
stack. A local attacker could exploit this flaw to cause a denial of
service or possibly other unspecified problems. (CVE-2017-7487)

Huang Weller discovered that the ext4 filesystem implementation in the
Linux kernel mishandled a needs-flushing-before-commit list. A local
attacker could use this to expose sensitive information.
(CVE-2017-7495)

It was discovered that an information leak existed in the
set_mempolicy and mbind compat syscalls in the Linux kernel. A local
attacker could use this to expose sensitive information (kernel
memory). (CVE-2017-7616).
