CVE-2026-8349 · Severity: medium · CVSS 4.3 · Published 2026-05-12

The omec-project Access and Mobility Management Function (AMF), a core component of 5G mobile networks, is vulnerable to a remote crash. An attacker can send a specially crafted location report message that causes the service to fail due to a memory error. This results in a denial-of-service condition, potentially disrupting mobile connectivity for users managed by the affected network node.

## Technical details

A vulnerability in the NGAP Message Handler of omec-project amf (up to version 2.1.1) allows for a remote denial-of-service. The flaw is rooted in a nil pointer dereference within the `HandleLocationReport` function in `ngap/handler.go`. An attacker with network access can trigger a panic by sending a malformed NGAP LocationReport message containing unexpected or missing protocol Information Elements (IEs). This leads to memory corruption/segmentation violation, crashing the AMF process. The issue has been addressed in version 2.2.0 and later by implementing comprehensive nil checks and input validation across the NGAP dispatcher and handlers.
