Vulnerability Title
Blutooth BR/EDR specification does not specify sufficient encryption key length and allows an attacker to influence key length negotiation
Source: NVD (National Vulnerability Database)
Vulnerability 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.
