CVE-2024-47673

Service interruption via commands after firmware shutdown

Published Oct 9, 2024 · Updated May 11, 2026

State-management flaw in Linux iwlwifi allows local users to interrupt wireless service through a stopped-firmware code path. The iwlmvm traffic-control work remains active after firmware shutdown, so recalculation reaches scan configuration and sends a host command through an inactive transport. Reachability requires an Intel wireless device using the iwlmvm driver and a stopped firmware state; the documented consequence is a kernel WARNING and loss of availability.
