CVE-2026-87679

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.

当 Brocade Fabric OS 版本早于 10.0.1 在处理端口通道（trunk）配置操作时，应用程序会将用户提供的列表字符串解析为动态分配的堆数组，而未对允许的最大元素数量实施边界检查。经过身份验证的管理员可通过构造包含过多列表分隔符的 REST API 请求利用此漏洞，导致堆损坏，进而可能引发服务崩溃或任意代码执行。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
When Brocade Fabric OS versions before 10.0.1 processes trunk configuration operations, the application parses user-supplied list strings into dynamically allocated heap arrays without enforcing boundary checks on the maximum allowable number of elements. An authenticated administrator can exploit this vulnerability via crafted REST API requests containing an excessive number of list delimiters, causing heap corruption that can result in service crash or arbitrary code execution.
