CVE-2022-48653

Local denial of service via double auxiliary unplug

Published Apr 28, 2024 · Updated May 11, 2026

Denial of service in the Linux kernel ice driver allows local users to trigger a scheduling fault during a peer-requested reset. The IDC reset callback calls ice_unplug_aux_dev even though ice_prepare_for_reset performs the same operation, causing device removal to schedule while atomic. Reachability requires the ice auxiliary-device path and a peer-initiated reset; the demonstrated result is a kernel scheduling BUG that can interrupt service.
