Ella Core is a 5G core designed for private networks. Prior to version 1.7.0, a deadlock in the AMF's SCTP notification handler causes the entire AMF control plane to hang until the process is restarted. An attacker with access to the N2 interface can cause Ella Core to hang, resulting in a denial of service for all subscribers. Version 1.7.0 adds deferred Radio cleanup in serveConn SCTP server so that every connection exit path removes the radio. Remove the stale-entry scan from SCTP Notification handling.
