AI Analysis
Technical Summary
CVE-2026-71676 describes a buffer overflow vulnerability in Open5GS version 2.7.0. This vulnerability is triggered remotely through the NAS 5GS decoder chain when the message type byte of a NAS PDU is mutated. Exploitation of this flaw can lead to a denial of service by crashing or destabilizing the affected system. No CVSS score or detailed exploit information is currently available, and no patch or remediation guidance has been provided.
Potential Impact
The vulnerability allows a remote attacker to cause a denial of service on systems running Open5GS v2.7.0 by sending malformed NAS PDUs that mutate the message type byte, leading to a buffer overflow in the NAS 5GS decoder chain. There is no information about privilege escalation, data disclosure, or code execution.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to the affected service and monitoring for anomalous NAS PDU messages if feasible.
