Ubuntu Security Notice USN-2172-4 covers a Linux kernel update fixing a race condition vulnerability that could grant unauthorized access to admin users
Matt T

Summary

Matt T. Yourst discovered an issue in the kvm subsystem. Local
users with permission to manipulate /dev/kvm can cause a denial
of service (hang) by providing an invalid cr3 value to the
KVM_SET_SREGS call.

For the stable distribution (lenny), these problems have been fixed
in version 72+dfsg-5~lenny2.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your kvm packages, and rebuild any kernel
modules you have built from a kvm-source package version.

Upgrade instructions
- --------------------

sources.list as given below:

apt-get upgrade
