CVE-2024-37987

Secure Boot bypass via undisclosed memory corruption

Published Jul 9, 2024 · Updated Feb 10, 2026

Secure Boot bypass in Microsoft Windows and Windows Server allows adjacent attackers to defeat boot integrity protections via crafted input. Microsoft identifies heap-based buffer overflow and type confusion weaknesses but has not disclosed the affected Secure Boot component or its exact input-handling failure. Exploitation requires adjacent access and user interaction, and success defeats the trust boundary protecting the boot process.
