      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: serial: fix ioctl hangup race\n\nThe tty ioctls can race with hangup and end up calling into a tty driver\nfor a device that is already gone or powered down.\n\nSerialise the callbacks using the tty port mutex and add the missing\nchecks to make sure the port has not been hung up before accessing port\ndriver data or hardware.\n\nThis specifically avoids dereferencing a NULL-pointer if a device is\ndisconnected during lengthy break signalling.\n\nNote that TIOCGICOUNT and TIOCMIWAIT do not access port driver data or\nhardware and are therefore not affected by the race.",
