In the Linux kernel, the following vulnerability has been resolved:
net: airoha: fix BQL imbalance in TX path
Fix a possible BQL imbalance in airoha dev xmit(), where inflight packets are accounted only for the AIROHA NUM TX RING netdev TX queues. The queue index is computed as:
qid = skb get queue mapping(skb) % ARRAY SIZE(qdma->q tx) txq = netdev get tx queue(dev, qid);
However, airoha qdma tx napi poll() accounts completions across all netdev TX queues (num tx queues), leading to inconsistent BQL accounting.
Also reset all netdev TX queues in the ndo stop callback.
