CVE-2026-8782: omec-project AMF null pointer dereference in NGAP Message Handler

CVE-2026-8782 · Severity: medium · CVSS 4.3 · Published 2026-05-18

The Access and Mobility Management Function (AMF) component of the omec-project, which manages mobile network connections, is vulnerable to a denial-of-service attack. An attacker can send specially crafted network messages that cause the service to crash. This results in a loss of availability for mobile network management operations until the service is restarted.

Technologies: github.com/omec-project/amf (Go), OMEC Project AMF. Vendors: Go, OMEC Project.

Technical details

A null pointer dereference vulnerability exists in the NGAP (Next Generation Application Protocol) message handler of the omec-project AMF. Specifically, the `HandleLocationReportingFailureIndication` function in `ngap/handler.go` fails to properly validate malformed NGAP messages, such as those with missing or invalid Information Elements (IEs). A remote attacker with network access to the AMF can send a crafted `LocationReportFailureIndication` message to trigger a panic (SIGSEGV), leading to a denial-of-service (DoS) condition. This issue was addressed in version 2.2.0 by implementing comprehensive nil-pointer checks and input validation across the NGAP dispatcher and NAS security parsing components.
