CVE-2026-8187: Resource Consumption in Open5GS
A flaw has been found in Open5GS up to 2.7.7. This impacts the function _gtpv1_u_recv_cb of the file src/upf/gtp-path.c of the component UPF. Executing a manipulation can lead to resource consumption. The attack may be performed from remote. The project was informed of the problem early through an issue report but has not responded yet.
AI Analysis
Technical Summary
This vulnerability in Open5GS (up to version 2.7.7) impacts the _gtpv1_u_recv_cb function within the src/upf/gtp-path.c file of the User Plane Function (UPF) component. An attacker can remotely manipulate inputs to trigger excessive resource consumption, potentially leading to denial of service conditions. The issue was reported early to the project, but no official fix or remediation guidance has been provided. The CVSS 4.0 base score is 6.9, indicating medium severity with network attack vector, no privileges or user interaction required, and limited impact on availability.
Potential Impact
Successful exploitation can lead to resource exhaustion on the affected Open5GS UPF component, which may degrade or disrupt service availability. There is no indication of data confidentiality or integrity impact. No known exploits have been observed in the wild to date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation has been published, users should monitor vendor communications for updates. Until a patch is available, consider limiting exposure of the UPF service to untrusted networks if feasible.
