Local privilege escalation via untrusted security input

Privilege escalation in Microsoft Windows 11 allows local users with low privileges to gain elevated access through the VBS Enclave. The VBS Enclave security decision relies on attacker-controlled input, but Microsoft has not disclosed the specific input, code locus, or validation failure. Exploitation requires local low-privileged access, no user interaction, and high-complexity conditions; success compromises confidentiality, integrity, and availability.
