CVE-2024-49971

Kernel crash via DML2 dummy Boolean overrun

Published Oct 21, 2024 · Updated May 11, 2026

Out-of-bounds write in the Linux kernel 6.11 AMD display driver allows local users to crash the system through display mode processing. The dml2_core_shared_mode_support and dml_core_mode_support paths take dummy_boolean[2] from a two-element array and then write through that pointer. Reachability requires local low-privileged access and an AMD display path using DML2; successful triggering can crash the kernel.
