Descriptions

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.

La función hci_uart_tty_open del controlador HCI UART (drivers/bluetooth/hci_ldisc.c) del kernel de Linux 2.6.36, y posiblemente otras versiones, no verifica si el tty tiene una operación de escritura, lo que permite a usuarios locales provocar una denegación de servicio (desreferenciación de puntero a NULL) a través de vectores relacionados con el controlador de Bluetooth.
