Overview

Affected versions of this package are vulnerable to Buffer Over-read via the processing of a malformed GATT packet. An attacker can crash the device and potentially execute arbitrary code by sending a specially crafted packet to the vulnerable device.

Note:

This is only exploitable if the device is in a state where it is accepting BLE connections.
