CVE-2020-12902

Local privilege escalation via arbitrary decrement

Published Nov 15, 2021 · Updated Sep 16, 2024

Arbitrary decrement in AMD Radeon Software allows local users to elevate privileges or interrupt systems running affected Windows 10 drivers. AMD identifies the defect only as an arbitrary-decrement weakness found during analysis of graphics-driver Escape calls, without naming the handler or decremented object. A low-privileged local process must reach the driver interface; successful exploitation elevates privileges or causes system-level denial of service.
