CVE-2026-117068
OpenAirInterface CN5G AMF Integer Underflow Denial of Service
Description
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.
