Name of the Vulnerable Software and Affected Versions (affected versions not specified)

Description A Time-of-check time-of-use (TOCTOU) race condition exists in the SMM communications buffer. This condition could allow a privileged attacker to bypass input validation and perform an out-of-bounds read or write. Successful exploitation could lead to a loss of confidentiality, integrity, or availability. A TOCTOU race condition occurs when a system checks a condition and then, before acting on that condition, another process changes it, leading to unexpected behavior.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
