AnalysisCVE.org

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: account non-AQL frames per peer rather than per link

The driver increments wcid->non_aql_packets when a frame goes to the hardware queue. The completion path decrements the counter again.

For an MLO peer, the hardware reports the completion on the link that it used for the transmission. This link can differ from the link that the driver queued the frame on. In that case, the increment and the decrement go to different link wcids, and the count drifts upwards until it blocks the station.

Keep the count on the wcid of the primary link, like the other peer-wide state.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
