CVE-2023-45866

A flaw was found in the HID Profile in BlueZ that opens doors for unauthorized connections, especially by devices like keyboards, to inject keystrokes without user confirmation. BlueZ lacks proper restrictions on non-bonded devices, creating a risk for attackers that are physically close to inject keystrokes and execute arbitrary commands when the device is in a discoverable state.

BlueZ was found to inadequately limit non-bonded devices from injecting HID events into the input subsystem. This vulnerability could permit a nearby attacker (physically proximate) to inject keystrokes and carry out arbitrary commands when the device is in discoverable mode.
