CVE-2026-87665
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 IKEv2（Internet Key Exchange，因特网密钥交换第二版）协议处理程序中存在基于栈的缓冲区溢出漏洞。当处理运行 IPsec 启用型 Fibre Channel over IP（FCIP）链路的扩展交换机或刀片模块上的初始 IKE 密钥交换请求时，会触发此漏洞。未认证的远程攻击者可通过发送一个包含过大 Nonce（随机数）负载的单条特制 UDP 数据包（端口 500）来利用该漏洞。成功利用后会导致拒绝服务（数据平面进程崩溃）。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A stack-based buffer overflow vulnerability exists in the Internet Key Exchange (IKEv2) protocol handler on Brocade Fabric OS versions before 10.0.1. The vulnerability occurs when processing initial IKE key exchange requests on extension switches or blades running IPsec-enabled Fibre Channel over IP (FCIP) circuits. An unauthenticated remote attacker can exploit this vulnerability by sending a single, specifically crafted UDP packet (Port 500) containing an oversized Nonce payload. Successful exploitation results in a denial of service (data-plane process crash)
