AnalysisCVE.org

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

netconsole: take target_cleanup_list_lock in drop_netconsole_target()

drop_netconsole_target() unlinks the target while only holding target_list_lock. However, when the underlying interface has been unregistered, netconsole_netdev_event() moves the target from target_list to target_cleanup_list, and netconsole_process_cleanups_core() walks that list under target_cleanup_list_lock only.

If a user removes the configfs target at the same time the cleanup worker is iterating target_cleanup_list, list_del() can corrupt the list because the two paths take disjoint locks while operating on the same list node.

Acquire target_cleanup_list_lock around the list_del() so the unlink is serialised against netconsole_process_cleanups_core() regardless of which list the target currently belongs to. The state transition that downgrades STATE_DEACTIVATED to STATE_DISABLED is left intact and is performed under the same combined locking, preserving the existing ordering with resume_target().

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.
