CVE-2022-2832Public exploitNetwork attack vector

Headless rendering crash via missing GPU back end

Published Aug 16, 2022 · Updated Aug 3, 2024

Null pointer dereference in Blender 3.3.0 allows remote attackers to crash headless rendering through an unavailable GPU back end. GPU_backend_init is reached indirectly from DRW_opengl_context_create without first confirming that a GPU back end exists, causing gl_backend.cc to dereference a null back-end pointer. Only headless builds are exposed; the upstream fix documents a rendering-process crash, not direct data disclosure or modification.
