CVE-2013-6367
The apic_get_tmcct 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.
Does this matter?
Lower severity and a low EPSS score (1.45%). Track it; it rarely justifies an emergency change on its own.
