Local kernel crash via invalid DML pointer copy
Published Dec 4, 2024 · Updated Aug 5, 2026
Double free in the Linux kernel AMD Display Core allows local users to crash an affected system after a DML allocation failure. After the allocation fails, dc_state_copy_internal shallow-copies invalid DML context pointers into a new state, whose release frees the same memory twice. Exploitation requires low-privileged local access and the AMD display driver path; the demonstrated consequence is a kernel crash and service interruption.
