Short explanation
CVE-2026-102185 is a high‑severity (CVSS 7.5) vulnerability in Juniper Networks’ Junos OS and Junos OS Evolved where an infinite loop in the routing protocol daemon (rpd) can be triggered by a remote attacker using EVPN multihoming with preference‑based designated‑forwarder election, causing a denial‑of‑service of the routing process.
Disrupting rpd halts routing updates, potentially affecting network stability and availability for organizations relying on Juniper equipment.
What should be done?
- Monitor Juniper advisories for a patch
- Apply vendor‑provided fixes when released
- Consider upgrading to a version where the issue is addressed
- Implement network segmentation to limit exposure
- Deploy intrusion detection for anomalous EVPN traffic
