In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_uart: Fix another race during initialization

Do not set 'HCI_UART_PROTO_READY' before call 'hci_uart_register_dev()'. Possible race is when someone calls 'hci_tty_uart_close()' after this bit is set, but 'hci_uart_register_dev()' wasn't done. This leads to access to uninitialized fields. To fix it let's set this bit after device was registered (as before patch c411c62cc133) and to fix previous problem let's add one more bit in addition to 'HCI_UART_PROTO_READY' which allows to perform power up without original bit set (pls see commit c411c62cc133).
