CVE-2017-12188 (retired)

Priority
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."
Ubuntu-Description
It was discovered that the KVM subsystem in the Linux kernel did not
properly keep track of nested levels in guest page tables. A local attacker
in a guest VM could use this to cause a denial of service (host OS crash)
or possibly execute arbitrary code in the host OS.
