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.
A flaw was found in the Linux kernel's airoha network driver. This vulnerability stems from an inconsistent accounting of inflight packets in the transmit (TX) path, leading to a Byte Queue Limit (BQL) imbalance. This issue could potentially result in network performance degradation or a denial of service (DoS) condition.
