Vulnerability from github – Published: 2024-08-26 12:31 – Updated: 2025-11-04 00:31

Details

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

wifi: nl80211: disallow setting special AP channel widths

Setting the AP channel width is meant for use with the normal 20/40/... MHz channel width progression, and switching around in S1G or narrow channels isn't supported. Disallow that.

Severity

5.5 (Medium)

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.
