## Summary Ella Core didn't enforce security rules on concurrent running of security procedures defined in TS 33.501 §6.9.5.1 — it could send a NAS Security Mode Command while an N2 handover was still pending (and vice versa). ## Impact Concurrent Security Mode Command and N2 handover produce a KgNB mismatch between the UE and target gNB, causing the handover to fail. Requires a stalled gNB + re-registration race to trigger. ## Fix Ella Core now enforces both rules from §6.9.5.1, blocking concurrent Security Mode Command and N2 handover procedures.
Update github.com/ellanetworks/core to 1.10.0 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in go. A low vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
