NVD Description

Note: Versions mentioned in the description apply only to the upstream bluez package and not the bluez package as distributed by Debian:11. See How to fix? for Debian:11 relevant fixed versions and status.

Bluetooth Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device (participating in the provisioning protocol) to identify the AuthValue used given the Provisioner’s public key, and the confirmation number and nonce provided by the provisioning device. This could permit a device without the AuthValue to complete provisioning without brute-forcing the AuthValue.
