CVE-2020-12895

Privilege escalation via Escape handler heap overflow

Published Nov 15, 2021 · Updated Sep 16, 2024

Pool/heap overflow in AMD Radeon Software before 20.11.2 allows local users to elevate privileges, disclose data, or crash Windows. The Windows graphics driver's Escape 0x110037 handler overruns a pool or heap buffer while processing a crafted escape request. A low-privileged local process must invoke the graphics escape interface; Radeon Pro Software for Enterprise before 21.Q1 is also affected.
