  "title": "comedi: comedi_parport: deal with premature interrupt",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  comedi: comedi_parport: deal with premature interrupt  Syzbot reported a general protection fault in \u0060comedi_get_is_subdevice_running()\u0060, which was called from the interrupt handler \u0060parport_interrupt()\u0060 in the \u0022comedi_parport\u0022 driver, but it does not currently have a C reproducer for the problem.  It\u0027s probably due to a premature interrupt for one of two reasons:  1. The driver sets up the interrupt handler before the comedi subdevices    used by the interrupt handler have been allocated, but does not    disable the interrupt in the parallel port\u0027s CTRL register first. 2. The driver uses a user-supplied I/O port base address which Syzbot    would have supplied, but it might not be backed by real parallel port    hardware.  Change the initialization order in the driver\u0027s comedi \u0022attach\u0022 handler (\u0060parport_attach()\u0060) so that the hardware registers are initialized before the interrupt handler is requested.  This should prevent premature interrupts occurring for real hardware.  Also add a test to the interrupt handler to ensure the comedi device is fully attached and return early if it isn\u0027t.",
