DescriptionIn 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.
