一、漏洞信息
漏洞编号:CVE-2026-94640
漏洞归属组件:rpcbind
漏洞归属的版本:1.2.5,1.2.6,1.2.7
CVSS评分:
BaseScore:0.0 None
Vector:
漏洞简述:
A flaw was found in rpcbind. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a large number of unique requests. The rpcbind service records previously unseen RPC (Remote Procedure Call) statistics in unbounded in-memory lists, leading to persistent memory growth and increased CPU usage. This can degrade or exhaust service availability.

二、漏洞分析结构反馈
影响性分析说明:
rpcbind 服务在处理远程过程调用(RPC)时,会将之前未出现过的RPC统计数据记录在一个无界的内存列表中。这导致系统内存会随着新请求的持续到达而不断增长,且无法自动回收。
