What is CVE-2025-48818?
A time-of-check time-of-use (TOCTOU) race condition in Microsoft Windows BitLocker leads to a potential security feature bypass. This vulnerability allows unauthorized attackers to exploit the system during a physical attack, thereby compromising sensitive data and system integrity. The flaw specifically arises in the timing between checking the security state and using it, creating an opening for exploitation if an attacker has physical access to the system.
