CVE-2024-27044

Local kernel crash via premature stream dereference

Published May 1, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux kernel 5.4 and later affected branches allows local users to crash the system through AMD display handling. dcn10_set_output_transfer_func uses its stream pointer before testing whether that pointer is NULL. Reaching the flaw requires local access and an AMD display path that invokes the function; the reported consequence is a system crash, not data disclosure or modification.
