An issue in the NGAP handler of free5gc v4.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted NAS PDU.
AnalysisAI
Denial-of-service in free5gc v4.0.1 allows remote unauthenticated attackers to crash the 5G core network's AMF component by sending a specially crafted NAS PDU to the NGAP handler. The vulnerability stems from improper resource allocation (CWE-770) in the NGAP message processing path, which when triggered drops all active 5G sessions handled by that AMF instance. …
