CVE-2022-23817
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
