A flaw was discovered in the requeuing of futexes in the Linux kernel. A
local user could exploit this flaw to cause a denial of service (system
crash) or possibly have other unspecified impact. (CVE-2012-6647)
A flaw was found in Linux kernel's validation of CIPSO (Common IP Security
Option) options set from userspace. A local user that can set a socket's
CIPSO options could exploit this flaw to cause a denial of service (crash
the system). (CVE-2013-0310)
