Vulnerability from fkie_nvd - Published: 2025-01-21 22:15 - Updated: 2025-03-18 21:15
Severity ?
6.5 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
