CVE-2026-42807
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.
Bosch Sensortec COINES_SDK（版本 2.10 至 2.12.2）中 PC 桥接协议解码器存在一个基于堆的缓冲区溢出漏洞，攻击者可借此导致拒绝服务（进程崩溃），甚至可能实现任意代码执行。 桥接解码器（{{bridge_decoder.c}}）直接信任外部设备提供的数据包长度字段，并将其转发至主机响应队列（{{mqueue_add_data}}），但未对目标缓冲区的边界进行校验。 一个恶意或被攻陷的 USB 或蓝牙低功耗（BLE）外设可以通告高达约 3 KB 的有效负载大小，超过了默认队列槽大小

Vulnerability Description
A heap-based buffer overflow vulnerability in the PC bridge protocol decoder of BoschSensortec COINES_SDK (versions 2.10 through 2.12.2) allows attackers to cause a denial of service (process crash) or potentially execute arbitrary code.
The bridge decoder ({{bridge_decoder.c}}) trusts the packet length field provided by the external device and forwards it to the host response queue ({{mqueue_add_data}}) without validating the bounds of the destination buffer.
A malicious or compromised USB or Bluetooth Low Energy (BLE) peripheral can advertise a payload size up to ~3 KB, which exceeds the default queue slot size of 255 bytes.
This results in an unbounded heap overwrite ({{memcpy}}), corrupting adjacent heap metadata on the host system when processing the device's response.
