An update that solves 13 vulnerabilities and has 31 fixes
is now available.

Description:

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 following non-security bugs were fixed:

– /proc/stat: convert to single_open_size() (bsc#928122).

(bsc#909312).

(bsc#927116).
– Btrfs: fix up bounds checking in lseek (bsc#927115).

context is forbidden, and destroy_worker() did so in the timer interrupt
with a nohz_full config. Preclude that possibility for both boot options.
