Name of the Vulnerable Software and Affected Versions Linux kernel versions through 3.17.2

Description A race condition in the kvm migrate pit timer function in the KVM subsystem allows guest OS users to cause a denial of service (host OS crash) by leveraging incorrect PIT emulation. A local guest user with access to the PIT i/o ports could use this flaw to crash the host.

Recommendations For Linux kernel versions through 3.17.2, consider disabling the kvm migrate pit timer function as a temporary workaround until a patch is available. Restrict access to the PIT i/o ports to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
