It has been rated as critical. Affected by this issue is an unknown part of the component ASP Secure OS Kernel. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Insufficient checking of memory buffer in AMD Secure Processor (ASP) Secure OS may allow an attacker with a malicious trusted application to read/write to the ASP Secure OS kernel virtual address space, potentially resulting in privilege escalation.

The advisory is available at amd.com. This vulnerability is handled as CVE-2022-23817 since 01/21/2022. The exploitation is known to be difficult. Local access is required to approach this attack. The technical details are unknown and an exploit is not available.

Upgrading eliminates this vulnerability.
