Vulnerability from github – Published: 2026-09-10 09:31 – Updated: 2026-09-10 09:31

Details

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.

Severity

6.8 (Medium)
