CVE-2026-87668
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 版本之前的诊断执行工具中存在一个基于栈的缓冲区溢出漏洞。在处理诊断操作的命令参数时，该工具将用户提供的输入标记化到内部参数数组中，但未对数组的最大容量强制执行边界检查。拥有管理权限的已认证用户可以通过提供包含过多标记化参数的恶意诊断命令字符串来利用此漏洞，从而导致内存覆盖，最终引发拒绝服务（进程崩溃）。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A stack-based buffer overflow vulnerability exists in the diagnostic execution utility of Brocade Fabric OS versions before 10.0.1. When processing command arguments for diagnostic operations, the utility tokenizes user-supplied input into an internal argument array without enforcing boundary checks on the maximum array capacity. An authenticated user with administrative access can exploit this vulnerability by supplying a crafted diagnostic command string containing an excessive number of tokenized arguments. This leads to a memory overwrite resulting in a denial of service (process crash).
