# Linux kernel: HID OneXPlayer driver races work callbacks during device removal

In the Linux HID OneXPlayer driver, device removal cancels delayed work without waiting for running callbacks, so a callback can touch the HID device after it is closed and stopped. The sources describe a use-after-teardown race in the kernel driver and do not say what an attacker can gain from it.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- unknown

## Fix

- Update to a Linux kernel build that includes the upstream commit replacing cancel_delayed_work() with cancel_delayed_work_sync() in oxp_hid_remove() (hid-oxp driver).

## From the sources

In the Linux kernel, the following vulnerability has been resolved:

HID: hid-oxp: use cancel_delayed_work_sync() in remove

oxp_hid_remove() uses cancel_delayed_work() for all three delayed work
items.  cancel_delayed_work() only dequeues a pending work item without
waiting for a currently executing callback to finish.  If any of the
work callbacks (oxp_rgb_queue_fn, oxp_btn_queue_fn, oxp_mcu_init_fn) is
running at the time of removal, the callback continues executing
concurrently with hid_hw_close() and hid_hw_stop(), accessing the HID
device after it has been closed and stopped.

Use cancel_delayed_work_sync() instead to ensure that any in-progress
work callback completes before device teardown proceeds.
