Local Secure Boot bypass via stack overflow
Published Jul 9, 2024 · Updated Feb 10, 2026
Stack-based buffer overflow in Microsoft Windows Secure Boot allows local users to bypass Secure Boot and compromise the boot chain. Microsoft identifies the weakness class but has not disclosed the affected buffer, malformed input, or operation that overruns it. Exploitation requires local access but no prior privileges or user interaction and permits untrusted boot code to undermine the pre-OS trust boundary.
