An issue was discovered in Bosch Sensortec COINES_SDK versions 2.0 through 2.11.  The host streaming API function {{coines_read_stream_sensor_data()}} fails to validate the boundaries of the caller-provided destination buffer. Internally, the stream processing mechanism in {{comm_intf_process_stream_response()}} discards the requested {{number_of_samples}} argument and copies the entirety of the streaming ring buffer's accumulated data into {{coines_stream_rsp_buf}}. Subsequently, {{coines_read_stream_sensor_data()}} unconditionally executes a {{memcpy}} of the ring buffer size into the caller-provided buffer without verifying if the destination memory allocation is large enough. A malicious or compromised hardware board connected via USB or BLE can exploit this by streaming a high volume of sensor samples, causing a heap or stack-based buffer overflow on the host desktop environment. This can result in a Denial of Service (DoS) or potential arbitrary code execution on the host machine.
