CVE-2026-53359

CVE-2026-53359 is a KVM/x86 shadow MMU use-after-free caused by a role mismatch when reusing shadow pages during a nested walk. The flaw arises when a PDE is modified and a 4KB leaf SPTE is installed on the new path, but the parent 2MB page’s direct flag and the shadow page’s role may not align, ...
