Title
drm/i915: Avoid lock inversion when pinning to GGTT on CHV/BXT+VTD
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Avoid lock inversion when pinning to GGTT on CHV/BXT+VTD
On completion of i915_vma_pin_ww(), a synchronous variant of
dma_fence_work_commit() is called. When pinning a VMA to GGTT address
space on a Cherry View family processor, or on a Broxton generation SoC
with VTD enabled, i.e., when stop_machine() is then called from
intel_ggtt_bind_vma(), that can potentially lead to lock inversion among
reservation_ww and cpu_hotplug locks.

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.
