Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix atomic calls in ath12k_mac_op_set_bitrate_mask() When I try to manually set bitrates: iw wlan0 set bitrates legacy-2.4 1 I get sleeping from invalid context error, see below. Fix that by switching to use recently introduced ieee80211_iterate_stations_mtx(). Do note that WCN6855 firmware is still crashing, I'm not sure if that firmware even supports bitrate WMI commands and should we consider disabling ath12k_mac_op_set_bitrate_mask() for WCN6855? But that's for another patch.

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.
