It has been rated as problematic. This issue affects some unknown functionality. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, and integrity. The summary by CVE is:

A compromised Trusted OS (TOS) driver could issue a malformed call that could potentially allow memory access outside the intended range resulting in loss of integrity.

The advisory is shared at amd.com. The identification of this vulnerability is CVE-2021-26380 since 01/29/2021. The exploitation is known to be difficult. An attack has to be approached locally. The exploitation needs additional levels of successful authentication. Neither technical details nor an exploit are publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
