Quick assessment

Affected
Arista Networks Wi-Fi Access Points
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.

在受影响的 Arista 接入点中，若配置了 VXLAN 隧道和 L2-proxy（这是 VESPA 用例特有的特定配置），与该隧道化 SSID 关联的无线客户端可以发送构造的恶意数据包，从而导致接入点在网络流量中泄露内存内容。该漏洞不具备内存写入原语，也无法实现远程代码执行。
