It has been classified as problematic. This affects an unknown part of the component fTPM Driver. The manipulation with an unknown input leads to a improper validation of specified quantity in input vulnerability. CWE is classifying the issue as CWE-1284. The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Improper access control in the fTPM driver in the trusted OS could allow a privileged attacker to corrupt system memory, potentially leading to loss of integrity, confidentiality, or availability.

It is possible to read the advisory at amd.com. This vulnerability is uniquely identified as CVE-2023-20515 since 10/27/2022. The exploitability is told to be easy. Attacking locally is a requirement. The exploitation needs additional levels of successful authentication. The technical details are unknown and an exploit is not publicly available.

Upgrading eliminates this vulnerability.
