Arbitrary code execution via APCB overwrite
Published Aug 13, 2024 · Updated Mar 18, 2025
An out-of-bounds write in APCB firmware for affected AMD Athlon and Ryzen processors allows local users to execute arbitrary code. Improper bounds checking lets attacker-controlled data write beyond an APCB entry and corrupt the firmware configuration block. Exploitation requires local, high-privilege access and high complexity; successful corruption can execute code outside the original security scope.

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?
