Linux kernel is vulnerable to denial of service(DoS) attacks. This occurs when the [io_ti] driver
is loaded, a local unprivileged attacker could request incorrect high transfer speed in the change_port_settings()
in the drivers/usb/serial/io_ti.c
so that the divisor value becomes zero and causes a system crash resulting in a denial of service.
