CVE ID:	CVE-2017-12188
Description:	arch/x86/kvm/mmu.c in the Linux kernel through 4.13.5, when nested virtualisation is used, does not properly traverse guest pagetable entries to resolve a guest virtual address, which allows L1 guest OS users to execute arbitrary code on the host OS or cause a denial of service (incorrect index during page walking, and host OS crash), aka an "MMU potential stack buffer overrun."
Test IDs:	1.3.6.1.4.1.25623.1.0.843374   1.3.6.1.4.1.25623.1.0.843375   1.3.6.1.4.1.25623.1.0.843371   1.3.6.1.4.1.25623.1.0.843370
