"Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges.
(CVE-2014-3153)

Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6
UDP Fragmentation Offload (UFO) processing. A remote attacker could
leverage this flaw to cause a denial of service (system crash).
(CVE-2013-4387)

Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP
Fragmentation Offload (UFO). An unprivileged local user could exploit
this flaw to cause a denial of service (system crash) or possibly gain
administrative privileges. (CVE-2013-4470)

A flaw was discovered in the Linux kernel's IPC reference counting. An
unprivileged local user could exploit this flaw to cause a denial of
service (OOM system crash). (CVE-2013-4483)

halfdog reported an error in the AMD K7 and K8 platform support in the
Linux kernel. An unprivileged local user could exploit this flaw on
AMD based systems to cause a denial of service (task kill) or possibly
gain privileges via a crafted application. (CVE-2014-1438)

Sasha Levin reported a bug in the Linux kernel's virtual memory
management subsystem. An unprivileged local user could exploit this
flaw to cause a denial of service (system crash). (CVE-2014-3122).
