      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: serial: fix port tear down use-after-free\n\nSome drivers for multiport devices access port driver data from\ncompletion handlers of shared URBs submitted at attach() or first open()\nand stopped at disconnect() or last close(), respectively.\n\nA simple NULL check before accessing the driver data makes sure that a\nport state container has at least been allocated, but a completion\nhandler can still race with port tear down.\n\nReorder the disconnect handling so that ports are not deregistered (and\ntheir driver data freed) until after all ports have been hung up and the\ndriver disconnect() callback has run so that all I/O has been stopped.",
