CVE-2026-42808
Description
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.
