Fix Version:
Severity: Standard
Applicable for: Wind River Linux LTS 17
Component/s: Kernel


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.
