      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: disallow multiple FENCE chunks in one submit\n\namdgpu_cs_pass1() dispatches on chunk_id once per chunk without\nrejecting repeated ids. p->uf_bo is a single-slot field, so a\nsubmission carrying two AMDGPU_CHUNK_ID_FENCE chunks runs\namdgpu_cs_p1_user_fence() twice, and the second run overwrites\np->uf_bo with a freshly referenced BO without dropping the reference\ntaken by the first.\n\namdgpu_cs_parser_fini() only unrefs the final p->uf_bo, so every FENCE\nchunk but the last leaks a BO reference. The leaked BO outlives handle\nclose and process exit.\n\nReject duplicate FENCE chunks the same way commit fec5f8e8c6bc\n(\"drm/amdgpu: disallow multiple BO_HANDLES chunks in one submit\") did\nfor p->bo_list.\n\n(cherry picked from commit 665b1fc2a1845206408f9a2c6da67101789edb82)",
