Description: | In change_port_settings in drivers/usb/serial/io_ti.c in the Linux kernel before 4.11.3, local users could cause a denial of service by division-by-zero in the serial device layer by trying to set very high baud rates. It was discovered that the USB serial device driver in the Linux kernel did not properly validate baud rate settings when debugging is enabled. A local attacker could use this to cause a denial of service (system crash).
