The kernel has been updated to the upstream 3.10.44 longterm kernel,
and fixes the following security issues:

The Netlink implementation in the Linux kernel through 3.14.1 does not
provide a mechanism for authorizing socket operations based on the
opener of a socket, which allows local users to bypass intended access
restrictions and modify network configurations by using a Netlink socket
for the (1) stdout or (2) stderr of a setuid program. (CVE-2014-0181)

media-device: fix infoleak in ioctl media_enum_entities()

The futex_requeue function in kernel/futex.c in the Linux kernel through
3.14.5 does not ensure that calls have two different futex addresses,
which allows local users to gain privileges via a crafted FUTEX_REQUEUE
command that facilitates unsafe waiter modification. (CVE-2014-3153)

kernel/auditsc.c in the Linux kernel through 3.14.5, when AUDITSYSCALL
is enabled with certain syscall rules, allows local users to obtain
potentially sensitive single-bit values from kernel memory or cause a
denial of service (OOPS) via a large value of a syscall number.

Andy Lutomirski has reported a vulnerability in Linux Kernel, which can
be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to an error related to checking Inode
capabilities, which can be exploited to conduct certain actions with
escalated privileges.
Successful exploitation requires a kernel built with user namespaces
(USER_NS) enabled. (CVE-2014-4014)
