CVE-2019-9506

CVE Details

Release Date:

2019-08-14

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.
