An integer underflow vulnerability in the NAS decoder of OpenAirInterface (OAI) CN5G AMF v2.2.1 allows an unauthenticated remote attacker to cause a denial of service (DoS) via crafted NAS Registration Requests containing a truncated SUCI in the 5GS Mobile Identity IE. Insufficient length validation in the DecodeSuci() function results in an out-of-bounds heap read, causing the AMF process to crash.
