CVE-2026-42808
Quick assessment
Affected
Bosch Sensortec COINES_SDK
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在博世森索泰克（Bosch Sensortec）COINES_SDK 版本 2.0 至 2.11 中发现了一个问题。 主机流式 API 函数 未对调用者提供的目标缓冲区边界进行校验。 内部而言， 中的流处理机制会忽略请求参数 ，并将流式环形缓冲区中累积的全部数据复制到 。 随后， 在未验证目标内存分配是否足够大的情况下，无条件地将环形缓冲区大小的数据通过 复制到调用者提供的缓冲区中。 通过 USB 或 BLE 连接的恶意或被入侵的硬件板卡，可以通过流式传输大量传感器采样数据来利用此漏洞，从而在主机桌面环境中引发堆栈

Vulnerability 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.
