In the Linux kernel, the following vulnerability has been resolved:
USB: serial: fix driver deregistration order
USB serial driver modules register one driver for the USB bus and one or more drivers for the ports on the USB serial bus.
When unloading a driver module, the USB driver must be deregistered before the USB serial bus drivers so that I/O is stopped before unbinding the ports to avoid use-after-free in completion handlers accessing port data.
Note that the "new_id" attributes must first be removed to prevent new ids from being added and triggering a probe of the USB driver after it has been deregistered.
