Local Secure Boot bypass
Published Apr 9, 2024 · Updated May 3, 2025
Secure Boot bypass in Microsoft Windows allows local users to compromise system confidentiality, integrity, and availability. Microsoft identifies an out-of-bounds read but has not disclosed the affected boot component, attacker-controlled input, or incorrect read operation. Exploitation requires low local privileges and no user interaction; success defeats the Secure Boot trust boundary and permits complete system compromise.
