A vulnerability classified as problematic was found in Open5GS up to 2.7.2. Affected by this vulnerability is the functi

A vulnerability classified as problematic was found in Open5GS up to 2.7.2. Affected by this vulnerability is the function amf_nsmf_pdusession_handle_update_sm_context of the file src/amf/nsmf-handler.c of the component AMF. The manipulation leads to denial of service.

The attack can be launched remotely. This vulnerability allows a single UE to crash the AMF, resulting in the complete loss of mobility and session management services and causing a network-wide outage. All registered UEs will lose connectivity, and new registrations will be blocked until the AMF is restarted, leading to a high availability impact.

The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue.
