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."
Affected configurations
• linux linux kernel (>= 4.6 < 4.9.57)
• linux linux kernel (>= 4.10 < 4.13.8)
