Vulnerability from github – Published: 2024-07-30 09:32 – Updated: 2024-12-11 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Add outer runtime_pm protection to xe_live_ktest@xe_dma_buf

Any kunit doing any memory access should get their own runtime_pm outer references since they don't use the standard driver API entries. In special this dma_buf from the same driver.

Found by pre-merge CI on adding WARN calls for unprotected inner callers:

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.
