DescriptionCVE.org
Time-of-check time-of-use (toctou) race condition in Windows BitLocker allows an unauthorized attacker to bypass a security feature with a physical attack.
Analysis
Time-of-check time-of-use (toctou) race condition in Windows BitLocker allows an unauthorized attacker to bypass a security feature with a physical attack.
Technical ContextAI
A race condition occurs when the behavior of software depends on the timing of events, such as the order of execution of threads or processes.
RemediationAI
Use proper synchronization mechanisms (locks, mutexes, atomic operations). Implement file locking for filesystem operations. Avoid TOCTOU patterns.
