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.

Attack Technique

Information Disclosure MEDIUM

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