CVE-2024-24445: n/a
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.
AI Analysis
Technical Summary
CVE-2024-24445 is a vulnerability in OpenAirInterface CN5G AMF (oai-cn5g-amf) versions <= 2.0.0 where the software improperly handles unsupported NGAP protocol messages. Specifically, when receiving a procedure code/presence field tuple that is unsupported, the system indexes into a null function pointer and dereferences it, causing a denial of service condition. This vulnerability requires network-adjacent attacker access and does not require privileges or user interaction. The CVSS 3.1 base score is 6.5, reflecting a medium severity denial of service impact with low attack complexity and no impact on confidentiality or integrity.
Potential Impact
An attacker with network-adjacent access can cause the AMF component of OpenAirInterface CN5G to crash or become unavailable by sending unsupported NGAP protocol messages. This results in denial of service, disrupting the availability of the affected network function. There is no impact on data confidentiality or integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict network access to the AMF component to trusted entities only to reduce exposure to network-adjacent attackers.
