CVE-2025-22116

Denial of service via invalid netdev unregister

Published Apr 16, 2025 · Updated May 11, 2026

Denial of service in the Linux kernel idpf driver 6.7 through 6.14.1 allows local users to disrupt availability during device removal. The idpf initialization path ignores a register_netdev() failure, then idpf_vport_dealloc() calls unregister_netdev() for an unregistered interface and triggers WARN_ON(). Reachability requires local low-privileged access and an idpf vport whose network-device registration fails; the reported consequence is a kernel warning during driver removal.
