  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: misc: uss720: unregister parport on probe failure\n\nuss720_probe() registers a parport before reading the 1284 register used\nto detect unsupported Belkin F5U002 adapters. If get_1284_register()\nfails, the error path drops the driver private data and the USB device\nreference, but leaves the parport device registered.\n\nLeaving the port registered is more than a private allocation leak:\nparport_register_port() has already reserved a parport number and\nregistered the parport bus device, while pp-\u003eprivate_data still points at\nthe private data that the common error path is about to release.\n\nUndo the pre-announce registration in the get_1284_register() failure\nbranch before jumping to the common private-data cleanup path. Clear\npriv-\u003epp first, matching the disconnect path and avoiding a stale pointer\nin the private data.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.",
