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.
