**Name of the Vulnerable Software and Affected Versions** Open5GS versions prior to 2.7.8 **Description** A remote denial of service issue exists within the AMF component. The flaw is located in the `amf nnrf handle nf discover()` function within the `src/amf/nnrf-handler.c` file. Manipulation of this function allows a remote attacker to cause the system to become unavailable. **Recommendations** Apply patch fb5f67703de0213fb9c6e6ef3b48b6c1707e9503 to resolve the issue. As a temporary mitigation, restrict access to the `amf nnrf handle nf discover()` function.
