Title
drm/xe: Don't free job in TDR
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Don't free job in TDR
Freeing job in TDR is not safe as TDR can pass the run_job thread
resulting in UAF. It is only safe for free job to naturally be called by
the scheduler. Rather free job in TDR, add to pending list.

No network or adjacent-network exposure exists.\nAC:L - The attacker controls both sides of the race \u2014 GPU batch duration determines when the fence signals, GuC CT saturation stalls `run_job()` past the TDR deadline, and the triggering \"exec queue closed immediately after last fence signaled\" pattern is described by the fix author as *common* \u2014 and it can be retried in a tight loop across many exec queues until won.\nPR:L - All required ioctls are marked `DRM_RENDER_ALLOW` with no `DRM_AUTH` or capability check, so any unprivileged local user (or sandboxed/containerized process such as a browser GPU process) holding an fd on the render node can trigger it.\nUI:N - The attacking process performs every step itself \u2014 create exec queue, submit a job with attacker-chosen execution time, close the queue \u2014 with no victim action required.\nS:U - The freed `xe_sched_job` and all subsequent accesses are kernel objects within the same security authority; no VM, IOMMU, or sandbox boundary is crossed by the corruption itself.\nC:H - The job is freed into a mergeable slab with no RCU delay, and the run_job worker then reads `sched_job-\u003es_fence`, `job-\u003efence`, and `job-\u003eq` from the reallocated memory, allowing an attacker who sprays the freed slot to steer dereferences and leak arbitrary kernel memory.\nI:H - After the free, `dma_fence_add_callback(fence, \u0026sched_job-\u003ecb, ...)` writes list pointers into the freed object and `drm_sched_job_done()`/`dma_fence_signal()` traverse callback lists and invoke `dma_fence_ops`/`dma_fence_cb-\u003efunc` pointers, giving a heap-spray-driven write and control-flow hijack primitive.\nA:H - The use-after-free corrupts the DRM scheduler\u0027s pending list and fence callback chains, reliably producing KASAN splats, oopses, and kernel panics; the buggy path additionally loses the job free, leaking memory and disturbing GPU submission state."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
