Summary

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF There is a KASAN: slab-use-after-free read in btusb_disconnect(). Calling "usb_driver_release_interface(&btusb_driver, data->intf)" will free the btusb data associated with the interface. The same data is then used later in the function, hence the UAF. Fix by moving the accesses to btusb data to before the data is free'd.
