CVE-2026-102179— Junos OS and Junos OS Evolved: An attacker causes a routing daemon crash when BGP EVPN RIB telemetry is used
Quick assessment
Affected
Juniper Networks Junos 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.
Juniper Networks Junos OS 和 Junos OS Evolved 的路由协议守护进程（rpd）中存在一个越界写入漏洞。拥有已配置的 BGP EVPN 对等体访问权限的攻击者，在订阅了 l2vpn-evpn RIB 遥测传感器时，可通过 BGP EVPN 路由处理导致拒绝服务。成功利用该漏洞会使 rpd 崩溃，并中断路由协议，直到该守护进程重新启动并完成重新收敛。

Vulnerability Title
Junos OS and Junos OS Evolved: An attacker causes a routing daemon crash when BGP EVPN RIB telemetry is used
Source: CVE Program / CVE List V5
Vulnerability Description
An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker with access to a configured BGP EVPN peer to cause a denial of service via BGP EVPN route processing when the l2vpn-evpn RIB telemetry sensor is subscribed. Successful exploitation can crash rpd and interrupt routing protocols until the daemon restarts and reconverges.
