Overview

CVE-2026-52983 is a high-severity vulnerability. It was published on June 24, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
