AnalysisCVE.org

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

ksmbd: scope session state changes to bound connections

ksmbd_all_conn_set_status() treats every connection whose transient binding flag is set as belonging to the target SessionId. A logoff or session replacement can consequently move an unrelated connection to NEED_RECONNECT or NEED_SETUP.

Pass the target session itself and select connections using either the connection-local session xarray or the session's permanent channel list. Use the same association test while waiting for requests to drain.

Serialize session-wide status changes under request_lock and do not overwrite EXITING or RELEASING. Protect the shutdown transition with the same lock so a concurrent session update cannot revive a closing connection.

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.
