CVE-2021-26360

ASP code execution via unauthorized register modification

Published Nov 9, 2022 · Updated May 1, 2025

Improper access control in AMD Radeon RX 6000 and PRO W6000 graphics products allows local users to execute code in the ASP. The vulnerable path accepts unauthorized changes to SoC security-configuration registers, enabling corruption of encrypted ASP memory contents. Low-privileged local access is required; AMD has not disclosed the interface or missing authorization check that exposes the register writes.
