arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before
3.17.2 on Intel processors does not ensure that the value in the CR4
control register remains the same after a VM entry, which allows host

(system disruption) by leveraging /dev/kvm access, as demonstrated by
PR_SET_TSC prctl calls within a modified copy of QEMU.
