No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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

wifi: iwlwifi: mvm: validate sta_id in BA window status notif

BA_WINDOW_STATUS_NOTIFICATION_ID extracts a 5-bit sta_id from the firmware notification and uses it to index fw_id_to_mac_id[] without bounds checking. Validate sta_id before array access to prevent out-of-bounds indexing.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
