Details

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

net: mvneta: Prevent out of bounds read in mvneta_config_rss()

The pp->indir[0] value comes from the user. It is passed to:

if (cpu_online(pp->rxq_def))

inside the mvneta_percpu_elect() function. It needs bounds checkeding to ensure that it is not beyond the end of the cpu bitmap.

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.
