CVE-2026-30080: n/a
OpenAirInterface v2.2.0 accepts Security Mode Complete without any integrity protection. Configuration has supported integrity NIA1 and NIA2. But if an UE sends initial registration request with only security capability IA0, OpenAirInterface accepts and proceeds. This downgrade security context can lead to the possibility of replay attack.
AI Analysis
Technical Summary
The vulnerability in OpenAirInterface v2.2.0 involves acceptance of Security Mode Complete messages lacking integrity protection when a User Equipment (UE) sends an initial registration request with security capability IA0 only. Although the configuration supports integrity algorithms NIA1 and NIA2, the system proceeds without enforcing them in this scenario, resulting in a downgraded security context. This flaw can facilitate replay attacks by allowing attackers to reuse valid messages without detection.
Potential Impact
The impact is a potential security downgrade that can lead to replay attacks, which may allow an attacker to reuse intercepted messages to disrupt or manipulate communication sessions. There is no indication of remote code execution or privilege escalation. The vulnerability affects the integrity and security assurance of the registration process in OpenAirInterface v2.2.0.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should monitor vendor communications for updates. No official mitigation or temporary fix is currently documented.
