Secure Boot security feature bypass
Published Apr 9, 2024 · Updated May 3, 2025
Secure Boot bypass in Microsoft Windows allows attackers to defeat boot-time code verification via crafted boot media. Microsoft maps the flaw to a stack-based buffer overflow but has not published the affected component or the incorrect operation performed on malformed input. Exploitation requires adjacent access and user interaction; successful exploitation permits untrusted boot code to evade the startup trust boundary.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
