Description
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.
A flaw was discovered in the Bluetooth protocol. An attacker within physical proximity to the Bluetooth connection could downgrade the encryption protocol to be trivially brute forced.
