Local privilege escalation through undisclosed Escape interface flaw
Published Nov 15, 2021 · Updated Sep 16, 2024
Privilege escalation in AMD Radeon Software before 20.11.2 and Radeon Pro Software before 21.Q2 allows local users to gain elevated access. The issue lies in the graphics driver's Escape call interface, but AMD has not published the faulty operation or accepted-input condition. A low-privileged local account is required; the available record does not specify the resulting privilege level or other effects.
