CVE-2025-30653

Routing service interruption via expired pointer dereference

Published Apr 9, 2025 · Updated Apr 9, 2025

Expired pointer dereference in rpd in Juniper Networks Junos OS and Junos OS Evolved allows attackers to crash and restart rpd via an LSP flap. When node-link-protection and transport-class are both configured, an MPLS LSP flap makes rpd dereference an expired pointer and restart. Reachability is adjacent and unauthenticated; continuous flapping can repeatedly crash rpd and sustain a routing-service interruption.
