Unauthenticated keystroke injection from BT on Android, Linux, macOS/iOS*

Unpatched devices are vulnerable under the following conditions:

• Android devices are vulnerable whenever Bluetooth is enabled
• Linux/BlueZ requires that Bluetooth is discoverable/connectable
• iOS and macOS are vulnerable when Bluetooth is enabled and a Magic Keyboard has been paired with the phone or computer

Time to disable Bluetooth on all your old android phones!
