Affected is an unknown code of the component Graphics Interface. The manipulation with an unknown input leads to a toctou vulnerability. CWE is classifying the issue as CWE-367. 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. This can cause the product to perform invalid actions when the resource is in an unexpected state. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A TOCTOU (Time-Of-Check to Time-Of-Use) in the graphics interface may allow an attacker to load registers repeatedly creating a race condition potentially leading to a loss of integrity.

The advisory is shared for download at amd.com. This vulnerability is traded as CVE-2022-23826 since 01/21/2022. The exploitability is told to be difficult. The attack needs to be approached locally. The exploitation needs additional levels of successful authentication. There are neither technical details nor an exploit publicly available.
