A Time-of-check time-of-use (TOCTOU) race condition in the AMD Secure Processor (ASP) could allow an attacker to corrupt memory resulting in loss of integrity, confidentiality, or availability.

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.
