CVE-2023-53064

Reboot hang via repeated iavf removal

Published May 2, 2025 · Updated May 27, 2026

Denial of service in the Linux iavf driver allows local users to hang system reboot on hosts with Intel E810 virtual functions. During shutdown, iavf_shutdown sets the adapter to __IAVF_REMOVE before ice_shutdown reaches iavf_remove, which accepts only running, down, or initialization-failed states and otherwise sleeps forever. The condition requires an E810 host with existing virtual functions and the affected callback order; successful triggering leaves reboot blocked indefinitely.
