The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search.

Security readout for executives and security teams

This vulnerability can crash OpenLDAP’s slapd service when the rwm overlay mishandles connection state during search activity. The business impact is service interruption, especially if LDAP supports login, directory lookup, or application authentication. The source bundle does not show active exploitation or a CVSS score. Exposure is most likely on systems running affected OpenLDAP versions with the rwm overlay enabled. Risk is higher for LDAP services reachable by untrusted networks or supporting business-critical authentication. Downstream product exposure should be confirmed through the cited vendor advisories. Treat as moderate priority, raised to high for internet-exposed or authentication-critical LDAP infrastructure. The issue is denial of service, not data theft, but directory outages can block user login and application access. Mitigation focus: Inventory OpenLDAP servers and identify affected versions.; Check whether the rwm overlay is enabled in slapd configuration.; Apply OpenLDAP security updates from the relevant OS or product vendor..
