Severity

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: Fix NULL pointer dereference in mt7996_init_tx_queues() When MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED are enabled and mt76 detects properly the Airoha NPU SoC, mt7996_init_tx_queues() will dereference a NULL WED pointer. Fix the issue by always passing the WED pointer from mt7996_dma_init().

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.
