Base vector

AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Open5GS MME versions prior to 2.6.4

Description The issue is related to a reachable assertion in the Uplink NAS Transport packet handler. A packet missing its MME UE S1AP ID field causes Open5GS to crash. An attacker may repeatedly send such packets to cause a denial of service.

Recommendations For versions prior to 2.6.4, update to version 2.6.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the Uplink NAS Transport packet handler to minimize the risk of exploitation. Avoid processing packets missing the MME UE S1AP ID field in the affected packet handler until the issue is resolved.
