Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
