CVE-2024-56753

Local service interruption via GFX9 memory leak

Published Dec 29, 2024 · Updated May 11, 2026

Memory leak in the AMD GFX9 graphics driver in Linux 6.12 allows local users to interrupt service during driver reinitialization. The gfx_v9_0_sw_fini function omits amdgpu_gfx_cleaner_shader_sw_fini(adev), leaving cleaner-shader allocations unreleased and GPU state uncleared. Exploitation requires low-privileged local access and GFX9 hardware, and the documented consequence is limited to availability.
