Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: airoha: fix BQL imbalance in TX path<br /> <br /> Fix a possible BQL imbalance in airoha_dev_xmit(), where inflight<br /> packets are accounted only for the AIROHA_NUM_TX_RING netdev TX<br /> queues. The queue index is computed as:<br /> <br /> qid = skb_get_queue_mapping(skb) % ARRAY_SIZE(qdma-&gt;q_tx)<br /> txq = netdev_get_tx_queue(dev, qid);<br /> <br /> However, airoha_qdma_tx_napi_poll() accounts completions across all<br /> netdev TX queues (num_tx_queues), leading to inconsistent BQL<br /> accounting.<br /> <br /> Also reset all netdev TX queues in the ndo_stop callback.
