Official description

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix RX data queuing of RRO 3.0 For RRO 3.0, RX data released from a RRO data queue should be put to the indicator queue. The frames are processed and completed in the context of the indicator queue NAPI, which only polls skbs queued on the MT_RXQ_RRO_IND list; frames queued under the data queue id are left sitting on that list until the data queue NAPI happens to run, stalling and reordering RX data.
