Privilege escalation via arbitrary memory page unmapping
Published May 15, 2026 · Updated May 15, 2026
Improper input validation in AMD Platform Management Framework on affected Ryzen processors allows local users to unmap memory pages. The PMF driver accepts an insufficiently validated request and unmaps attacker-selected memory pages; AMD has not disclosed the responsible interface or function. Low-privileged local access is required, and successful exploitation can corrupt or disrupt memory mappings or elevate privileges and expose protected data.
