CVE-2024-49918

System crash via AMD display NULL dereference

Published Oct 21, 2024 · Updated May 11, 2026

NULL pointer dereference in the AMD display driver in Linux 4.15 through 6.10.13 and 6.11 through 6.11.2 allows local users to crash the system. The dcn32_acquire_idle_pipe_for_head_pipe_in_layer function can receive a null head_pipe pointer but dereferences it during an assertion instead of returning NULL. A low-privileged local user must reach the affected AMD display path; exploitation interrupts availability without reported data disclosure or modification.
