GHSA-9H59-P45G-445H
Vulnerability from github – Published: 2026-03-26 22:13 – Updated: 2026-03-27 21:51Summary
A deadlock in the AMF's SCTP notification handler causes the entire AMF control plane to hang until the process is restarted.
Impact
An attacker with access to the N2 interface can cause Ella Core to hang, resulting in a denial of service for all subscribers.
Fix
Add 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.
