Ben Hutchings reported a flaw in the Linux kernel with some network drivers
that support TSO (TCP segment offload). A local or peer user could exploit
this flaw to cause a denial of service. (CVE-2012-3412)

Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel
implementation of RDS sockets. A local unprivileged user could potentially
use this flaw to read privileged information from the kernel.
(CVE-2012-3430)

A flaw was discovered in the madvise feature of the Linux kernel's memory
subsystem. An unprivileged local use could exploit the flaw to cause a
denial of service (crash the system). (CVE-2012-3511)");
