CVE-2026-90101Hinoki check available

Kernel crash via incorrect hardware-monitoring device argument

Published Sep 17, 2026 · Updated Sep 17, 2026

Device misuse in Linux 6.7 bnxt_en allows attackers to disrupt service via hardware-monitoring events that trigger undefined behavior. The bnxt_hwmon_notify_event function passes a PCI device to hwmon_notify_event instead of the registered hardware-monitoring device, creating a reported kernel crash risk. The path requires registered hardware monitoring and a recognized thermal-threshold event; public sources do not explain how attackers force that event.
