CVE-2024-41093

Kernel crash via null framebuffer object

Published Jul 29, 2024 · Updated May 11, 2026

NULL pointer dereference in the AMDGPU virtual display driver in Linux allows local users to crash the kernel through a crafted framebuffer state. The atomic-check path reads state->fb->obj[0] directly without verifying that the framebuffer contains a GEM object; the correction uses drm_gem_fb_get_obj() and rejects a null result. Low-privileged local access and use of the AMDGPU virtual display path are required; the reported consequence is a host crash, with no data disclosure or modification.
