8.8 HIGH

Published 2026-09-17 · Updated 2026-09-18

AI risk analysis

Summary
This vulnerability allows concurrent report processing with probe operations, leading to potential use-after-free conditions when probe fails, impacting input handling in the Linux kernel.
Exploitability
Exploitation requires concurrent report processing and probe failure, making it moderately difficult. Precondition is the presence of concurrent report callbacks during probe failure.
Blast radius
If exploited, it could lead to denial of service or privilege escalation through use-after-free conditions.
Detection
No reliable host or network indicator is derivable from the published description.
Prioritized remediation
Upgrade to the Linux kernel version 6.1.17 or later.

NVD description

In the Linux kernel, the following vulnerability has been resolved: HID: synchronize input before cleaning up a failed probe hid_device_io_start() allows reports to run concurrently with probe. If the probe subsequently fails, __hid_device_probe() releases driver resources and clears hdev->driver without first excluding those report callbacks. For example, a report may enter hidraw_report_event() while the failure path frees the associated hidraw object, leading to a use-after-free when the report takes the object's list lock. Stop input before performing failed-probe cleanup. This reacquires driver_input_lock and waits for any report callback already in progress.
