Details

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

wifi: mt76: mt7921e: fix crash in chip reset fail

In case of drv own fail in reset, we may need to run mac_reset several times. The sequence would trigger system crash as the log below.

Because we do not re-enable/schedule "tx_napi" before disable it again, the process would keep waiting for state change in napi_diable(). To avoid the problem and keep status synchronize for each run, goto final resource handling if drv own failed.

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.
