CVE-2026-14623 · Severity: medium · CVSS 4.3 · Published 2026-07-04

A vulnerability exists in the Access and Mobility Management Function (AMF) of the omec-project, which is a core component of 5G mobile networks. An attacker can send a specially crafted network message that causes the service to crash. This results in a denial of service, potentially disrupting mobile connectivity for users relying on that network segment.

## Technical details

A vulnerability in the omec-project AMF (up to version 2.1.1) is caused by a NULL pointer dereference within the RRCInactiveTransitionReport function of the NGAP Message Handler. The issue arises when the component fails to properly validate malformed NGAP input, leading to a Go runtime panic and subsequent process crash. An attacker with network access can trigger this condition by sending a specific sequence of manipulated NGAP messages. The vulnerability is addressed in commit 34bc6724acc97dba1f8691e586da95b042cb612d, which introduces nil-pointer checks and improved input validation. Version 2.2.0 and later contain the fix.
