AnalysisCVE.org

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

wifi: mt76: mt7996: do not attach hif2 WED when the main WED attach failed

If the WED attach for the primary PCIe function fails, the probe path still attached wed_hif2 for the secondary function, leaving the device in an inconsistent half-WED configuration that crashes later. The hif2 call also re-enabled hwrro_mode, which the failed primary attach had just turned off.

Skip the hif2 WED setup when the primary WED device is not active.

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.
