OpenAirInterface 核心网络 v2.2.1 版本在 OAI CN5G UDM 的 Nudm_UEAU 生成认证数据接口中存在基于栈的缓冲区溢出漏洞。该 UDM 将攻击者可控的 和 参数传递给 函数，该函数将任意长度的十六进制字符串转换为固定大小的栈缓冲区，且未对目标缓冲区的大小进行验证。任何能够访问 SBI 接口并拥有有效 SUPI 的非认证攻击者，均可提交过大的参数值，从而覆盖相邻的栈内存、破坏栈保护值（stack canary），最终导致 UDM 进程终止。

Vulnerability Description
OpenAirInterface Core Network v2.2.1 has a stack-based buffer overflow vulnerability in the OAI CN5G UDM Nudm_UEAU Generate Authentication Data endpoint. The UDM passes attacker-controlled resynchronizationInfo.rand and auts values to conv::hex_str_to_uint8(), which converts arbitrary-length hex strings into fixed-size stack buffers without validating the destination size. An unauthenticated attacker with access to the SBI interface and a valid SUPI can submit an oversized value to overwrite adjacent stack memory, corrupt the stack canary, and terminate the UDM process.
