CVE-2020-12987

Kernel-address disclosure via heap information leak

Published Jun 11, 2021 · Updated Sep 17, 2024

Information disclosure in AMD Radeon Software before 20.7.1 allows local users to obtain kernel pool addresses and bypass KASLR. AMD identifies a heap information leak in its Windows 10 graphics driver but has not disclosed the affected API, code path, or operation that returns kernel pool addresses. The issue also affects Radeon Pro Software for Enterprise before 21.Q1; low-privilege local access is required, and only address-layout data is reported exposed.
