CVE-2026-30080 (GCVE-0-2026-30080)
Vulnerability from nvd – Published: 2026-04-08 00:00 – Updated: 2026-04-09 20:45
VLAI
Summary
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.

CVE-2026-30075 (GCVE-0-2026-30075)
Vulnerability from nvd – Published: 2026-04-08 00:00 – Updated: 2026-04-09 20:48
VLAI
Summary
OpenAirInterface Version 2.2.0 has a Buffer Overflow vulnerability in processing UplinkNASTransport containing Authentication Response containing a NAS PDU with oversize response (For example 100 byte). The response is decoded by AMF and passed to the AUSF component for verification. AUSF crashes on receiving this oversize response. This can prohibit users from further registration and verification and can cause Denial of Services (DoS).

CVE-2026-30079 (GCVE-0-2026-30079)
Vulnerability from nvd – Published: 2026-04-07 00:00 – Updated: 2026-04-09 13:47
VLAI
Summary
In OpenAirInterface V2.2.0 AMF, Out of sequence messages causes incorrect state transition during UE registration procedure. This allows authentication to be bypassed completely. If a SecurityModeComplete message is sent after InitialUERegistration, a registration reject is received followed by a registration accept! This leads the UE to be registered without proper authentication.

CVE-2026-30080 (GCVE-0-2026-30080)
Vulnerability from cvelistv5 – Published: 2026-04-08 00:00 – Updated: 2026-04-09 20:45
VLAI
Summary
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.

CVE-2026-30075 (GCVE-0-2026-30075)
Vulnerability from cvelistv5 – Published: 2026-04-08 00:00 – Updated: 2026-04-09 20:48
VLAI
Summary
OpenAirInterface Version 2.2.0 has a Buffer Overflow vulnerability in processing UplinkNASTransport containing Authentication Response containing a NAS PDU with oversize response (For example 100 byte). The response is decoded by AMF and passed to the AUSF component for verification. AUSF crashes on receiving this oversize response. This can prohibit users from further registration and verification and can cause Denial of Services (DoS).

CVE-2026-30079 (GCVE-0-2026-30079)
Vulnerability from cvelistv5 – Published: 2026-04-07 00:00 – Updated: 2026-04-09 13:47
VLAI
Summary
In OpenAirInterface V2.2.0 AMF, Out of sequence messages causes incorrect state transition during UE registration procedure. This allows authentication to be bypassed completely. If a SecurityModeComplete message is sent after InitialUERegistration, a registration reject is received followed by a registration accept! This leads the UE to be registered without proper authentication.
