CVE-2013-1935

A certain Red Hat patch to the KVM subsystem in the kernel package before
2.6.32-358.11.1.el6 on Red Hat Enterprise Linux (RHEL) 6 does not properly
implement the PV EOI feature, which allows guest OS users to cause a denial
of service (host OS crash) by leveraging a time window during which
interrupts are disabled but copy_to_user function calls are possible.
