## Overview

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

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
