NVD Description

Note: Versions mentioned in the description apply only to the upstream dtb-al package and not the dtb-al package as distributed by SLES.

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.
