kernel is vulnerable to denial of service. A flaw was found in the way the KVM subsystem of a Linux kernel handled PIT (Programmable Interval Timer) IRQs (interrupt requests) when there was no virtual interrupt controller set up. A malicious user in the kvm group on the host could force this situation to occur, resulting in the host crashing.
