CVE-2026-52983 is a high-severity flaw (CVSS 7.5) affecting linux kernel. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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
