Secure Boot bypass by local administrators
Published Apr 9, 2024 · Updated May 3, 2025
Secure Boot protection failure in affected Microsoft Windows builds allows local users with high privileges to bypass Secure Boot. Microsoft has not disclosed the affected Secure Boot component or the operation that mishandles untrusted boot content. Exploitation requires local administrative access; success defeats expected Secure Boot enforcement for the affected startup path.
