CVE-2026-94582

Quick assessment

Affected
Brocade Fabric OS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Brocade Fabric OS 10.0.1 之前版本中的 Fabric Shortest Path First (FSPF) 协议组件所使用内部诊断和路由验证例程中存在一个内存缓冲区溢出漏洞。虽然该代码路径属于内部诊断功能的一部分，无法通过标准用户界面或 CLI 管理命令直接访问，但输入处理缺陷会导致传入的或内部路由的诊断状态载荷超出已分配的内存边界。攻击者若能够将此内部诊断漏洞与其他漏洞结合利用，可导致基于堆或栈的内存越界，从而引发守护进程崩溃（拒绝服务），或在路由守护进程上下文中实现任意代码执行。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A memory buffer overflow vulnerability exists in the internal diagnostic and route validation routines used by the Fabric Shortest Path First (FSPF) protocol component of Brocade Fabric OS versions before 10.0.1. While this code path is part of internal diagnostic functionality and is not directly accessible via standard user interfaces or CLI management commands, an input processing flaw allows incoming or internally routed diagnostic state payloads to exceed allocated memory boundaries. An attacker that is able to chain or link other vulnerabilities to exploit this internal diagnostic could cause a heap- or stack-based memory overrun, resulting in a daemon crash (Denial of Service) or potential arbitrary code execution within the context of the routing daemon.
