CVE-2026-14624: omec-project amf denial of service in NGAP handler

CVE-2026-14624 · Severity: medium · CVSS 4.3 · Published 2026-07-04

Technologies: OMEC Project AMF. Vendors: OMEC Project.

Executive brief

A vulnerability in the Access and Mobility Management Function (AMF) of the omec-project 5G core network can allow a remote attacker to crash the service. The AMF is a critical component that manages mobile device access and mobility within a 5G network; an exploit would result in a denial-of-service, preventing mobile users from connecting or maintaining their sessions. This issue is caused by the software failing to properly handle specifically malformed network messages.

Technical details

A NULL pointer dereference vulnerability (CWE-404/CWE-476) exists in the NGAP handler of the omec-project AMF. The root cause is located in /go/src/amf/ngap/handler.go, specifically within the HandlePDUSessionResourceModifyIndication function, where the code fails to validate the existence of an SmContext before attempting to access its SmfUri. A remote attacker can trigger a kernel panic (SIGSEGV) by sending a malformed PDUSessionResourceModifyIndication message with invalid information elements. This leads to a complete crash of the AMF service. The issue has been addressed in the 2.2.0 release and subsequent patches.
