"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.

"An information leak in the Linux kernel was discovered that could leak
the high 16 bits of the kernel stack address on 32-bit Kernel Virtual
Machine (KVM) paravirt guests. A user in the guest OS could exploit
this leak to obtain information that could potentially be used to aid
in attacking the kernel. (CVE-2014-8134)

Rabin Vincent, Robert Swiecki, Russell King discovered that the ftrace
subsystem of the Linux kernel does not properly handle private syscall
numbers. A local user could exploit this flaw to cause a denial of
service (OOPS). (CVE-2014-7826)

A flaw in the handling of malformed ASCONF chunks by SCTP (Stream
Control Transmission Protocol) implementation in the Linux kernel was
discovered. A remote attacker could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-3673)

A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream
Control Transmission Protocol) implementation in the Linux kernel was
discovered. A remote attacker could exploit this flaw to cause a
denial of service (panic). (CVE-2014-3687)

It was discovered that excessive queuing by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel can cause
memory pressure. A remote attacker could exploit this flaw to cause a
denial of service. (CVE-2014-3688)

Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a flaw in
how the perf subsystem of the Linux kernel handles private systecall
numbers. A local user could exploit this to cause a denial of service
(OOPS) or bypass ASLR protections via a crafted application.
(CVE-2014-7825)

Andy Lutomirski discovered a flaw in how the Linux kernel handles
pivot_root when used with a chroot directory. A local user could
exploit this flaw to cause a denial of service (mount-tree loop).
(CVE-2014-7970)

Dmitry Monakhov discovered a race condition in the
ext4_file_write_iter function of the Linux kernel's ext4 filesystem. A
local user could exploit this flaw to cause a denial of service (file
unavailability). (CVE-2014-8086)

The KVM (kernel virtual machine) subsystem of the Linux kernel
miscalculates the number of memory pages during the handling of a
mapping failure. A guest OS user could exploit this to cause a denial
of service (host OS page unpinning) or possibly have unspecified other
impact by leveraging guest OS privileges. (CVE-2014-8369)

Andy Lutomirski discovered that the Linux kernel does not properly
handle faults associated with the Stack Segment (SS) register on the
x86 architecture. A local attacker could exploit this flaw to cause a
denial of service (panic). (CVE-2014-9090).

"* A flaw was found in the way the Linux kernel's XFS file system
handled replacing of remote attributes under certain conditions. A
local user with access to XFS file system mount could potentially use
this flaw to escalate their privileges on the system. (CVE-2015-0274,
Important)

* It was found that the Linux kernel's KVM implementation did not
ensure that the host CR4 control register value remained unchanged
across VM entries on the same virtual CPU. A local, unprivileged user
could use this flaw to cause denial of service on the system.
(CVE-2014-3690, Moderate)

* A flaw was found in the way Linux kernel's Transparent Huge Pages
(THP) implementation handled non-huge page migration. A local,
unprivileged user could use this flaw to crash the kernel by migrating
transparent hugepages. (CVE-2014-3940, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing
functionality of the Linux kernel's perf subsystem. A local,
unprivileged user could use this flaw to crash the system.
(CVE-2014-7825, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing
functionality of the Linux kernel's ftrace subsystem. On a system with
ftrace syscall tracing enabled, a local, unprivileged user could use
this flaw to crash the system, or escalate their privileges.
(CVE-2014-7826, Moderate)

* A race condition flaw was found in the Linux kernel's ext4 file
system implementation that allowed a local, unprivileged user to crash
the system by simultaneously writing to a file and toggling the
O_DIRECT flag using fcntl(F_SETFL) on that file. (CVE-2014-8086,
Moderate)

* A flaw was found in the way the Linux kernel's netfilter subsystem
handled generic protocol tracking. As demonstrated in the Stream
Control Transmission Protocol (SCTP) case, a remote attacker could use
this flaw to bypass intended iptables rule restrictions when the
associated connection tracking module was not loaded on the system.
(CVE-2014-8160, Moderate)

* It was found that due to excessive files_lock locking, a soft lockup
could be triggered in the Linux kernel when performing asynchronous
I/O operations. A local, unprivileged user could use this flaw to
crash the system. (CVE-2014-8172, Moderate)

* A NULL pointer dereference flaw was found in the way the Linux
kernel's madvise MADV_WILLNEED functionality handled page table
locking. A local, unprivileged user could use this flaw to crash the
system. (CVE-2014-8173, Moderate)

* An information leak flaw was found in the Linux kernel's IEEE 802.11
wireless networking implementation. When software encryption was used,
a remote attacker could use this flaw to leak up to 8 bytes of
plaintext. (CVE-2014-8709, Low)

* A stack-based buffer overflow flaw was found in the
TechnoTrend/Hauppauge DEC USB device driver. A local user with write
access to the corresponding device could use this flaw to crash the
kernel or, potentially, elevate their privileges on the system.
(CVE-2014-8884, Low)

* Users of kernel modules may need to upgrade the module to maintain
compatibility.

The system must be rebooted for this update to take effect."
