Privilege escalation via improper parameter handling
Published Nov 9, 2022 · Updated Sep 17, 2024
Privilege escalation in ASP drivers for AMD Ryzen Embedded R1000, R2000, V1000, V2000, and 5000 allows local users to alter integrity. The drivers improperly handle attacker-controlled parameters, but AMD has not disclosed the affected interface or exact validation failure. Exploitation requires existing privileged local access; privilege elevation and integrity loss are the only vendor-reported consequences.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
