Host crash or code execution via unchecked copy
Published Sep 10, 2026 · Updated Sep 10, 2026
Buffer overflow in the Bosch Sensortec COINES SDK streaming API 2.0 through 2.11 allows attackers to crash the host via a malicious USB or BLE board. The comm_intf_process_stream_response() function ignores number_of_samples and fills coines_stream_rsp_buf with all accumulated ring-buffer data; coines_read_stream_sensor_data() then copies that full size into the caller buffer without checking its capacity. Exploitation requires a malicious or compromised connected board to stream excessive samples, and the resulting host memory corruption also enables arbitrary code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
