CVE-2024-49906

System crash via premature plane-state dereference

Published Oct 21, 2024 · Updated May 11, 2026

NULL pointer dereference in the AMD display driver in Linux allows local users to crash the system through display state handling. The check in dcn20_hwseq.c dereferences pipe_ctx->plane_state before testing whether plane_state is NULL. A local low-privilege user must reach the AMD display code path; exploitation provides no data access or modification but can crash the host.
