Title
wifi: mt76: fix RXDMAD_C buffer recycling race
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix RXDMAD_C buffer recycling race
The RXDMAD_C buffers come from the RRO data queues' page pools, which are
bound to a different NAPI, so the direct page-pool recycle used here could
race the owning NAPI; take the non-direct path as is already done for WED
RX queues.
Severity
No CVSS data available.

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.
