Local privilege escalation via missing integrity check
Published Jul 8, 2025 · Updated Feb 26, 2026
Missing integrity validation in Microsoft Windows VBS Enclave allows local administrators to elevate privileges on affected releases. Microsoft identifies the locus as VBS Enclave integrity checking but has not published the unchecked object, verification path, or resulting privilege level. Exploitation requires existing high privileges and local access, and no user interaction is required.
