Details

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

virtio: delete vq in vp_find_vqs_msix() when request_irq() fails

When request_irq() fails, error path calls vp_del_vqs(). There, as vq is present in the list, free_irq() is called for the same vector. That causes following splat:

Detection rules are retrieved from Rulezet.

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.
