0 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. Join the discussion | CVE Database V5 | 04/07/2026, 00:00:00 UTC Added: 04/07/2026, 15:01:15 UTC |
0 OpenAirInterface V2.2.0 AMF crashes when it receives an NGAP message containing an invalid procedure code or an invalid PDU-type, such as sending a successfulOutcome message when an InitiatingMessage is required. This vulnerability can cause a denial of service due to the crash. Join the discussion | CVE Database V5 | 04/06/2026, 00:00:00 UTC Added: 04/06/2026, 14:00:30 UTC |
0 A stack overflow in the sctp_server::sctp_receiver_thread component of OpenAirInterface CN5G AMF (oai-cn5g-amf) up to v2.0.0 allows attackers to cause a Denial of Service (DoS) by repeatedly establishing SCTP connections with the N2 interface.

0 OpenAirInterface CN5G AMF (oai-cn5g-amf) <= 2.0.0 contains a null dereference in its handling of unsupported NGAP protocol messages which allows an attacker with network-adjacent access to the AMF to carry out denial of service. When a procedure code/presence field tuple is received that is unsupported, OAI indexes into a null function pointer and subsequently dereferences it.

0 Improper file descriptor handling for closed connections in OpenAirInterface CN5G AMF (oai-cn5g-amf) up to v2.0.0 allows attackers to cause a Denial of Service (DoS) by repeatedly establishing SCTP connections with the N2 interface.

0 An uninitialized pointer dereference in the ngap_handle_pdu_session_resource_setup_response routine of OpenAirInterface CN5G AMF (oai-cn5g-amf) up to v2.0.0 allows attackers to cause a Denial of Service (DoS) via a crafted PDU Session Resource Setup Response.

0 A NULL pointer dereference in the ngap_app::handle_receive routine of OpenAirInterface CN5G AMF (oai-cn5g-amf) up to v2.0.0 allows attackers to cause a Denial of Service (DoS) via a crafted NGAP message.

0 A buffer overflow in the ngap_amf_handle_pdu_session_resource_setup_response function of oai-cn5g-amf up to v2.0.0 allows attackers to cause a Denial of Service (DoS) via a PDU Session Resource Setup Response with an empty Response Item list.
