No patch reference has been recorded for CVE-2023-20514, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.
What does CVE-2023-20514 affect?
CVE-2023-20514 affects AMD Secure Processor, AMD processors with ASP. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2023-20514?
Apply firmware updates and mitigations when available
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Privileged attacker can feed arbitrary memory to the ASP trusted execution environment, enabling arbitrary code execution in the TEE.
