Title

idpf: return 0 size for RSS key if not supported

Summary

In the Linux kernel, the following vulnerability has been resolved: idpf: return 0 size for RSS key if not supported Returning -EOPNOTSUPP from function returning u32 is leading to cast and invalid size value as a result. -EOPNOTSUPP as a size probably will lead to allocation fail. Command: ethtool -x eth0 It is visible on all devices that don't have RSS caps set.

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.
