Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Open5GS v2.8.0 的 HTTP/2 SBI 服务器中存在内存耗尽漏洞。重复的头部名称会导致先前分配的头部字符串发生泄漏；而 HPACK 压缩机制允许未经身份验证的远程攻击者通过极小的请求触发数万个重复的头部字段。持续发送精心构造的请求可导致堆内存持续增长，最终耗尽进程内存并终止受影响的 Open5GS 网络功能，从而造成拒绝服务（DoS）。

Vulnerability Description
A memory exhaustion issue exists in Open5GS v2.8.0 in the HTTP/2 SBI server. Repeated header names cause previously allocated header strings to be leaked, and HPACK compression allows an unauthenticated remote attacker to trigger tens of thousands of duplicate headers with a small request. Repeated crafted requests can cause persistent heap growth, exhaust process memory, and terminate the affected Open5GS network function, resulting in denial of service.
