The Bluetooth Classic implementation in the Cypress WICED BT stack through
2.9.0 for CYW20735B1 devices does not properly handle the reception of
LMP_max_slot with a greater ACL Length after completion of the LMP setup
procedure, allowing attackers in radio range to trigger a denial of service
(firmware crash) via a crafted LMP packet.
