Recommendation: Monitor — no exploitation signal at the moment.

Open5GS MME versions <= 2.6.4 contain a reachable assertion in the `Uplink NAS Transport` packet handler. A packet missing its `MME_UE_S1AP_ID` field causes Open5gs to crash; an attacker may repeatedly send such packets to cause denial of service.
