Other sources

The apicgettmcct function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via crafted modifications of the TMICT value.

— Launchpad

Under guest controllable circumstances apicgettmcct will execute a divide by zero.

A privileged guest user could use this flaw to crash the host.
