Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
OpenAirInterface (OAI) CN5G AMF v2.2.1 版本中的 NAS 解码器存在整数截断漏洞。该漏洞允许未经身份验证的远程攻击者通过构造恶意的 NAS 注册请求（其中 5GS 移动身份信息单元 IE 包含格式错误的 IMEISV），引发拒绝服务（DoS）攻击。具体而言， 函数将 32 位的长度值截断为 16 位，从而绕过了长度验证机制，导致 函数中出现堆越界读操作，最终可能致使 AMF 进程崩溃。

Vulnerability Description
An integer truncation 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 malformed IMEISV in the 5GS Mobile Identity IE. The Type6NasIe::Validate() function truncates a 32-bit length value to 16 bits, bypassing length validation and causing an out-of-bounds heap read in DecodeImeisv(), which can crash the AMF process.
