Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference via the HCI host layer when validation of HCI connection complete or HCI command TX buffer is missing. An attacker can cause a crash or denial of service by sending malformed or unexpected Bluetooth controller responses.
