Impact
In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: properly drop the usb interface reference on disconnect When the device is disconnected from the driver, there is a "dangling" reference count on the usb interface that was grabbed in the probe callback. Fix this up by properly dropping the reference after we are done with it.
