CVE-2024-49989

System crash via duplicate encoder destruction

Published Oct 21, 2024 · Updated May 11, 2026

Double free in the Linux kernel AMD display driver allows local users to crash the system during amdgpu module unload. The link_destroy path frees encoders for flexible links even though those links borrow DIG resources from inflexible endpoints, so teardown destroys the same encoder twice. Triggering the kernel crash requires permission to unload the amdgpu module and a display topology containing flexible endpoints that share those resources.
