Local privilege escalation via undisclosed authentication flaw
Published Dec 10, 2024 · Updated Jun 9, 2026
Improper authentication in Microsoft Windows VBS Enclave allows local users with low privileges to elevate privileges through unspecified vectors. Microsoft has not published the vulnerable component, the authentication operation it performs incorrectly, or the resulting privilege level. Exploitation requires local access and existing low privileges; successful exploitation compromises enclave confidentiality, integrity, and availability.
