Описание
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.
Отчет
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise MRG 2 as they did not provide support for the KVM subsystem.
