The hci_uart_tty_open function in the HCI UART driver
(drivers/bluetooth/hci_ldisc.c) in the Linux kernel 2.6.36, and
possibly other versions, does not verify whether the tty has a write
operation, which allows local users to cause a denial of service (NULL
pointer dereference) via vectors related to the Bluetooth driver.
