Authenticated data writes via missing privilege enforcement
Published May 15, 2026 · Updated May 15, 2026
Improper access control in the AMD Secure Processor on affected accelerator cards allows remote authenticated users to write data. The ASP accepts an input value for an undisclosed function and completes the write without enforcing the caller's required privilege. Network access with low privileges is required; affected models are Instinct MI25, MI210, MI250, Radeon PRO V520, and V620, and successful writes can compromise integrity and interrupt availability.
