CVE-2025-60011Network attack vector

Routing disruption via malformed BGP attribute propagation

Published Jan 15, 2026 · Updated Jan 15, 2026

Improper exceptional-condition handling in Junos OS and Junos OS Evolved rpd allows remote attackers to disrupt downstream routing. The daemon erroneously modifies a specific optional transitive BGP attribute before forwarding it, causing peers to treat the attribute as malformed and terminate their BGP sessions. An existing BGP session must deliver the attribute; the resulting session loss produces routing churn rather than a crash of the affected device.
