CVE-2025-45480

Host communication disruption via boundary-port misclassification

Published Sep 13, 2026 · Updated Sep 13, 2026

Link-spoofing weakness in Floodlight 71fe8a7 allows attackers to disrupt host communication through a spoofed link. The controller misclassifies a spoofed-link port as non-boundary, causing host traffic to follow attacker-influenced topology state. Reachability requires the ability to inject or relay link-discovery traffic between connected switches; the documented consequence is host-communication interruption.
