"Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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

* An integer overflow flaw was found in the way the Linux kernel's
netfilter connection tracking implementation loaded extensions. An
attacker on a local network could potentially send a sequence of
specially crafted packets that would initiate the loading of a large
number of extensions, causing the targeted system in that network to
crash. (CVE-2014-9715, Moderate)

* A stack-based buffer overflow flaw was found in the Linux kernel's
early load microcode functionality. On a system with UEFI Secure Boot
enabled, a local, privileged user could use this flaw to increase
their privileges to the kernel (ring0) level, bypassing intended
restrictions in place. (CVE-2015-2666, Moderate)

* It was found that the Linux kernel's ping socket implementation did
not properly handle socket unhashing during spurious disconnects,
which could lead to a use-after-free flaw. On x86-64 architecture
systems, a local user able to create ping sockets could use this flaw
to crash the system. On non-x86-64 architecture systems, a local user
able to create ping sockets could use this flaw to escalate their
privileges on the system. (CVE-2015-3636, Moderate)

* It was found that the Linux kernel's TCP/IP protocol suite
implementation for IPv6 allowed the Hop Limit value to be set to a
smaller value than the default one. An attacker on a local network
could use this flaw to prevent systems on that network from sending or
receiving network packets. (CVE-2015-2922, Low)

Red Hat would like to thank Nathan Hoad for reporting the
CVE-2014-9715 issue.

This update also fixes several bugs. Refer to the following
Knowledgebase article for further information :

https://access.redhat.com/articles/1474193

All kernel users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The system
must be rebooted for this update to take effect."

"The SUSE Linux Enterprise 12 kernel was updated to version 3.12.43 to
receive various security and bugfixes.

Following security bugs were fixed :

  - CVE-2014-3647: arch/x86/kvm/emulate.c in the KVM
    subsystem in the Linux kernel through 3.17.2 did not
    properly perform RIP changes, which allowed guest OS
    users to cause a denial of service (guest OS crash) via
    a crafted application (bsc#899192).

  - CVE-2014-8086: Race condition in the
    ext4_file_write_iter function in fs/ext4/file.c in the
    Linux kernel through 3.17 allowed local users to cause a
    denial of service (file unavailability) via a
    combination of a write action and an F_SETFL fcntl
    operation for the O_DIRECT flag (bsc#900881).

  - CVE-2014-8159: The InfiniBand (IB) implementation did
    not properly restrict use of User Verbs for registration
    of memory regions, which allowed local users to access
    arbitrary physical memory locations, and consequently
    cause a denial of service (system crash) or gain
    privileges, by leveraging permissions on a uverbs device
    under /dev/infiniband/ (bsc#914742).

  - CVE-2015-1465: The IPv4 implementation in the Linux
    kernel before 3.18.8 did not properly consider the
    length of the Read-Copy Update (RCU) grace period for
    redirecting lookups in the absence of caching, which
    allowed remote attackers to cause a denial of service
    (memory consumption or system crash) via a flood of
    packets (bsc#916225).

  - CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux
    kernel before 3.19 used an incorrect data type in a
    sysctl table, which allowed local users to obtain
    potentially sensitive information from kernel memory or
    possibly have unspecified other impact by accessing a
    sysctl entry (bsc#919007).

  - CVE-2015-2042: net/rds/sysctl.c in the Linux kernel
    before 3.19 used an incorrect data type in a sysctl
    table, which allowed local users to obtain potentially
    sensitive information from kernel memory or possibly
    have unspecified other impact by accessing a sysctl
    entry (bsc#919018).

  - CVE-2015-2666: Fixed a flaw that allowed crafted
    microcode to overflow the kernel stack (bsc#922944).

  - CVE-2015-2830: Fixed int80 fork from 64-bit tasks
    mishandling (bsc#926240).

  - CVE-2015-2922: Fixed possible denial of service (DoS)
    attack against IPv6 network stacks due to improper
    handling of Router Advertisements (bsc#922583).

  - CVE-2015-3331: Fixed buffer overruns in RFC4106
    implementation using AESNI (bsc#927257).

  - CVE-2015-3332: Fixed TCP Fast Open local DoS
    (bsc#928135).

  - CVE-2015-3339: Fixed race condition flaw between the
    chown() and execve() system calls which could have lead
    to local privilege escalation (bsc#928130).

  - CVE-2015-3636: Fixed use-after-free in ping sockets
    which could have lead to local privilege escalation
    (bsc#929525).

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