KVM in the Linux kernel before 4.8.12, when I/O APIC is enabled, does not
properly restrict the VCPU index, which allows guest OS users to gain host
OS privileges or cause a denial of service (out-of-bounds array access and
host OS crash) via a crafted interrupt request, related to
arch/x86/kvm/ioapic.c and arch/x86/kvm/ioapic.h.
