CVE-2025-60007

Local service outage via crafted chassis command

Published Jan 15, 2026 · Updated Jan 15, 2026

NULL pointer dereference in Juniper Networks Junos OS chassisd allows local users to interrupt service via crafted show chassis options. Chassisd dereferences a null pointer while processing specific option combinations, causing the daemon to crash and restart. Low-privileged CLI access is required; the restart reinitializes every chassis component except the Routing Engine, causing a complete but automatically recovering outage.
