CVE-2024-24427Network attack vector

AMF service crash via malformed SUCI assertion

Published Jan 21, 2025 · Updated Jan 23, 2025

Reachable assertion in the Open5GS AMF 2.6.4 and earlier allows remote attackers to crash the service via a crafted NAS packet. The amf_ue_set_suci function passes a malformed mobile identity to ogs_nas_5gs_suci_from_mobile_identity, then asserts that the failed parse returned a SUCI. The packet must reach the RAN-facing AMF path; assertion termination interrupts AMF service before subscriber authentication.
