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.
Weakness
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check.
