CVE ID:	CVE-2010-4242
Description:	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.
Test IDs:	1.3.6.1.4.1.25623.1.0.69222   1.3.6.1.4.1.25623.1.0.68715   1.3.6.1.4.1.25623.1.0.69169   1.3.6.1.4.1.25623.1.0.68724   1.3.6.1.4.1.25623.1.0.68992
