CVE-2021-47639
CVE-2021-47639 affects the Linux kernel KVM x86/mmu code. The issue arises when unmapping a guest frame number (gfn) range in the TDP MMU: both valid and invalid SPTE roots can be zapped, but invalid roots aren’t consistently cleared in mmu_notifier paths. This can leave references to freed pages...
