Ubuntu Security Notice USN-2135-2 outlines vulnerabilities in the kernel impacting ARM architectures, providing crucial guidance for updates and associated threats.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-ti-omap4: Linux kernel for OMAP4

Details:

Mathy Vanhoef discovered an error in the the way the ath9k driver was

handling the BSSID masking. A remote attacker could exploit this error to

discover the original MAC address after a spoofing atack. (CVE-2013-4579)

Andrew Honig reported an error in the Linux Kernel's Kernel Virtual Machine

(KVM) VAPIC synchronization operation. A local user could exploit this flaw

to gain privileges or cause a denial of service (system crash).

(CVE-2013-6368)

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)

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  linux-image-3.2.0-1444-omap4    3.2.0-1444.63

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
