CVE-2020-12905

Local information disclosure via graphics Escape read

Published Nov 15, 2021 · Updated Sep 17, 2024

Out-of-bounds read in AMD Radeon Software before 20.11.2 allows local users to disclose arbitrary information through Escape 0x3004403. AMD identifies the affected locus as the Windows 10 graphics driver's Escape 0x3004403 handler but has not disclosed the unchecked size or index operation. The affected range also includes Radeon Pro Software for Enterprise before 21.Q2, and exploitation requires low-privilege local access.
