Description Josh Bressers 2004-09-21 14:42:55 EDT
drivers/input/serio/serport.c can lead to kernel panic in serio code
followed by jbd's panic (probably due to random memory write, I don't
       now) and/or system lockup.

        Steps to exploit it:
        process 1:
            open() a tty device;
            TIOCSETD it to N_MOUSE;
            read() it. it will block.
        after that, process 2:
            open() the same device;
            TIOCSETD it to 0;
            TIOCSETD it to N_MOUSE; (not sure if it's necessary)
            kill() process 1;
