    value:
"* 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."
