Title
drm/i915: mark requests for GuC virtual engines to avoid use-after-free
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: mark requests for GuC virtual engines to avoid use-after-free
References to i915_requests may be trapped by userspace inside a
sync_file or dmabuf (dma-resv) and held indefinitely across different
proceses. To counter-act the memory leaks, we try to not to keep
references from the request past their completion.
On the other side on fence release we need to know if rq->engine
is valid and points to hw engine (true for non-virtual requests).
To make it possible extra bit has been added to rq->execution_mask,
for marking virtual engines.
(cherry picked from commit 280410677af763f3871b93e794a199cfcf6fb580)

To counter-act the memory leaks, we try to not to keep\nreferences from the request past their completion.\nOn the other side on fence release we need to know if rq-\u003eengine\nis valid and points to hw engine (true for non-virtual requests).\nTo make it possible extra bit has been added to rq-\u003eexecution_mask,\nfor marking virtual engines.\n\n(cherry picked from commit 280410677af763f3871b93e794a199cfcf6fb580)"

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

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.
