  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_uart: clear HCI_UART_SENDING when write_work is canceled  HCI_UART_SENDING bit in tx_state means write_work is pending and blocks queueing it again.  Currently this bit is not cleared when canceling the work in hci_uart_close(), which blocks future writes when device is reopened later if write_work was pending.  Fix by clearing HCI_UART_SENDING when canceling the work.  Also make clearing of tx_skb safe by using disable_work_sync + enable_work instead of just cancel_work_sync.  hci_uart_flush() purges the proto tx queue so we can cancel the pending write_work there, instead of doing it just in hci_uart_close().  Re-enable and possibly requeue the work after queue flush.",
