Discussion

Bluetooth is a personal area network (PAN) technology. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the kernel to dynamically load a protocol handler by opening a socket using the protocol.

Check Content

Verify the Bluetooth protocol handler is prevented from dynamic loading:

# grep "install bluetooth /bin/true" /etc/modprobe.conf /etc/modprobe.conf.local /etc/modprobe.d/*

If no result is returned, this is a finding.

Fix Text

Prevent the Bluetooth protocol handler for dynamic loading:

# echo "install bluetooth /bin/true" >> /etc/modprobe.conf.local
