Details

Dmitry Monakhov reported a race condition flaw the Linux ext4 filesystem
that can expose stale data. An unprivileged user could exploit this flaw to
cause an information leak. (CVE-2012-4508)

Dave Jones discovered that the Linux kernel’s socket subsystem does not
correctly ensure the keepalive action is associated with a stream socket. A
local user could exploit this flaw to cause a denial of service (system
crash) by creating a raw socket. (CVE-2012-6657)

An information leak was discovered in the Linux kernel’s tkill and tgkill
system calls when used from compat processes. A local user could exploit
this flaw to examine potentially sensitive kernel memory. (CVE-2013-2141)

Kees Cook discovered a format string vulnerability in the Broadcom B43
wireless driver for the Linux kernel. A local user could exploit this flaw
to gain administrative privileges. (CVE-2013-2852)
