Vulnerability from github – Published: 2026-09-17 18:32 – Updated: 2026-09-17 18:32

Details

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

dmaengine: dw-edma: Serialize abort state updates

dw_edma_abort_interrupt() drops vc.lock before changing request and status. issue_pending() can acquire the lock in that small window, observe the old busy state, and skip starting queued descriptors. Then the abort handler overwrites the channel status as idle, leaving the new descriptors stranded for good.

Keep descriptor completion and the state transition in the same critical section.

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.
