AI-suggested
Until a fix is available, avoid connecting untrusted or potentially compromised USB or BLE peripherals to systems running affected versions of COINES_SDK. Monitor vendor channels for updates and apply official patches once released.
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.
Impact
Successful exploitation can cause denial of service by crashing the affected process or potentially allow arbitrary code execution on the host system. The vulnerability impacts confidentiality, integrity, and availability as indicated by the CVSS vector (C:H/I:H/A:H). No known exploits in the wild have been reported.

Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #16
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
