"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_uart: fix null-ptr-deref in hci_uart_write_work\n\nhci_uart_set_proto() sets HCI_UART_PROTO_INIT before calling\nhci_uart_register_dev(), which calls proto->open() to initialize\nhu->priv. However, if a TTY write wakeup occurs during this window,\nhci_uart_tx_wakeup() may schedule write_work before hu->priv is\ninitialized, leading to a NULL pointer dereference in\nhci_uart_write_work() when proto->dequeue() accesses hu->priv.\n\nThe race condition is:\n\n CPU0 CPU1\n ---- ----\n hci_uart_set_proto()\n set_bit(HCI_UART_PROTO_INIT)\n hci_uart_register_dev()\n tty write wakeup\n hci_uart_tty_wakeup()\n hci_uart_tx_wakeup()\n schedule_work(&hu->write_work)\n proto->open(hu)\n // initializes hu->priv\n hci_uart_write_work()\n hci_uart_dequeue()\n proto->dequeue(hu)\n // accesses hu->priv (NULL!)\n\nFix this by moving set_bit(HCI_UART_PROTO_INIT) after proto->open()\nsucceeds, ensuring hu->priv is initialized before any work can be\nscheduled."
