CVE-2026-42807

Bosch Sensortec / COINES_SDK PUBLISHED

Description (CNA)

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.
