The hub_activate function in drivers/usb/core/hub.c in the Linux kernel
before 4.3.5 does not properly maintain a hub-interface data structure,
which allows physically proximate attackers to cause a denial of service
(invalid memory access and system crash) or possibly have unspecified other
impact by unplugging a USB hub device.
