CVE-2019-9506  (opens in a new tab)
CWE-327  (opens in a new tab)

How to fix?

Upgrade SLES:15.1 kernel-devel to version 4.12.14-197.21.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

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.
