CVE-2026-7586 Details
Description
A weakness has been identified in Open5GS up to 2.7.7. Affected is the function ogs_id_get_value of the file /src/amf/nudm-handler.c of the component AMF. This manipulation causes denial of service. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
A denial-of-service vulnerability has been identified in Open5GS versions through 2.7.7, specifically within the AMF component. The issue arises in the 'ogs_id_get_value' function of the 'nudm-handler.c' file, where the application crashes due to a malformed GPSI entry. This vulnerability can be exploited remotely, causing the AMF process to abort during a standard UE registration flow when the 'nudm-sdm' 'am-data' response includes an incorrect GPSI format, such as 'msisdn' instead of the required 'msisdn-...' identifier.
