CVE-2025-21838

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

usb: gadget: core: flush gadget workqueue after device removal

device_del() can lead to new work being scheduled in gadget->work workqueue. This is observed, for example, with the dwc3 driver with the following call stack: device_del() gadget_unbind_driver() usb_gadget_disconnect_locked() dwc3_gadget_pullup() dwc3_gadget_soft_disconnect() usb_gadget_set_state() schedule_work(&gadget->work)

Move flush_work() after device_del() to ensure the workqueue is cleaned up.
