CVE-2026-90329 (CVSS 8.8)

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.
