CVE-2026-97479Hinoki check available

Kernel warning via invalid unbinding-state check

Published Sep 24, 2026 · Updated Sep 24, 2026

Improper exceptional-condition handling in Linux before 6.18.53 allows attackers to trigger a kernel warning during PCI device removal. The driver core function __device_links_no_driver treats a supplier in the legitimate DL_DEV_UNBINDING state as invalid while recursively unbinding linked consumers. Reaching the warning requires the affected device-link topology and driver removal; the published record reports a warning, not memory corruption or unauthorized data access.
