CVE-2026-42808 (GCVE-0-2026-42808)

Vulnerability from nvd – Published: 2026-09-10 09:05 – Updated: 2026-09-10 13:17

Summary

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.

CVE-2026-42807 (GCVE-0-2026-42807)

Vulnerability from nvd – Published: 2026-09-10 09:05 – Updated: 2026-09-10 15:00

Summary

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.

Severity

CVE-2026-42806 (GCVE-0-2026-42806)

Vulnerability from nvd – Published: 2026-09-10 09:04 – Updated: 2026-09-10 15:00

Summary

An out-of-bounds read vulnerability was discovered in the Bosch BME690 SensorAPI (C-driver) in version v1.0.3 and prior, specifically within the field data parsing logic in read_all_field_data (bme69x.c). The driver prefetches heater configuration registers into a contiguous 30-byte stack buffer (set_val) mapping IDAC, RES_HEAT, and GAS_WAIT tables. When parsing sensor field data, the gas_index is extracted using a 4-bit mask (0..15) but lacks boundary verification against the valid range (0..9). An attacker or a compromised peripheral mimicking a sensor on the I2C/SPI bus could return a payload with a gas index value of 10 or higher. This causes the driver to perform an out-of-bounds array access (set_val[20 + gas_index]), reading up to 6 bytes past the stack buffer. The leaked out-of-bounds byte is then written into the public gas_wait field, which may lead to measurement corruption or leak adjacent stack memory when telemetered or logged.

CVE-2026-42805 (GCVE-0-2026-42805)

Vulnerability from nvd – Published: 2026-09-10 09:04 – Updated: 2026-09-10 15:01

Summary

A stack-based buffer overflow vulnerability exists in the Bosch Sensortec BHI385 SensorAPI (C library) within the debug message parser function bhi385_parse_debug_message (located in bhi385_parse.c). The function parses FIFO events and extracts an 8-bit message length directly from the attacker-controlled event payload (callback_info->data_ptr[0]) without enforcing bounds checks or clamping the value. When copying the payload into a fixed-size stack buffer of 17 bytes (uint8_t debug_msg[17]) via memcpy, providing a length byte greater than 16 causes the function to write past the allocated stack boundary. This memory corruption can be triggered by a malicious or compromised sensor or bus participant, leading to a firmware crash, Denial of Service (DoS), or potentially the execution of arbitrary code via adjacent stack data corruption.

CVE-2026-42804 (GCVE-0-2026-42804)

Vulnerability from nvd – Published: 2026-09-10 08:56 – Updated: 2026-09-10 15:01

Summary

A stack-based buffer overflow vulnerability exists in the Bosch Sensortec BHI360 SensorAPI(C-Library) in versions up to and including commit d6b200416a. The vulnerability is located within the FIFO parsing and debug logging subsystem inside the function bhi360_parse_debug_message() in bhi360_parse.c (lines 1852-1875). The parser trusts the first payload byte of a debug frame as the message length (msg_length) and copies that many bytes into a fixed-size 17-byte stack buffer (debug_msg) via memcpy without performing any bounds checking. A locally or physically positioned attacker (e.g., via a malicious sensor, counterfeit hardware module, or a Man-in-the-Middle on the communication bus) can exploit this vulnerability by injecting a crafted debug frame with a length byte exceeding 16. This corrupts adjacent stack data, including the saved return address. Furthermore, because the overflowed buffer is subsequently passed to a printf-style logging sink, the attacker can supply format string specifiers (e.g., %n) to execute arbitrary code on the host microcontroller/SoC or cause a reliable system crash (Denial of Service).

CVE-2026-42808 (GCVE-0-2026-42808)

Vulnerability from cvelistv5 – Published: 2026-09-10 09:05 – Updated: 2026-09-10 13:17

Summary

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.

CVE-2026-42807 (GCVE-0-2026-42807)

Vulnerability from cvelistv5 – Published: 2026-09-10 09:05 – Updated: 2026-09-10 15:00

Summary

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.

Severity

CVE-2026-42806 (GCVE-0-2026-42806)

Vulnerability from cvelistv5 – Published: 2026-09-10 09:04 – Updated: 2026-09-10 15:00

Summary

An out-of-bounds read vulnerability was discovered in the Bosch BME690 SensorAPI (C-driver) in version v1.0.3 and prior, specifically within the field data parsing logic in read_all_field_data (bme69x.c). The driver prefetches heater configuration registers into a contiguous 30-byte stack buffer (set_val) mapping IDAC, RES_HEAT, and GAS_WAIT tables. When parsing sensor field data, the gas_index is extracted using a 4-bit mask (0..15) but lacks boundary verification against the valid range (0..9). An attacker or a compromised peripheral mimicking a sensor on the I2C/SPI bus could return a payload with a gas index value of 10 or higher. This causes the driver to perform an out-of-bounds array access (set_val[20 + gas_index]), reading up to 6 bytes past the stack buffer. The leaked out-of-bounds byte is then written into the public gas_wait field, which may lead to measurement corruption or leak adjacent stack memory when telemetered or logged.

CVE-2026-42805 (GCVE-0-2026-42805)

Vulnerability from cvelistv5 – Published: 2026-09-10 09:04 – Updated: 2026-09-10 15:01

Summary

A stack-based buffer overflow vulnerability exists in the Bosch Sensortec BHI385 SensorAPI (C library) within the debug message parser function bhi385_parse_debug_message (located in bhi385_parse.c). The function parses FIFO events and extracts an 8-bit message length directly from the attacker-controlled event payload (callback_info->data_ptr[0]) without enforcing bounds checks or clamping the value. When copying the payload into a fixed-size stack buffer of 17 bytes (uint8_t debug_msg[17]) via memcpy, providing a length byte greater than 16 causes the function to write past the allocated stack boundary. This memory corruption can be triggered by a malicious or compromised sensor or bus participant, leading to a firmware crash, Denial of Service (DoS), or potentially the execution of arbitrary code via adjacent stack data corruption.

Severity

8.4 (High)

CVE-2026-42804 (GCVE-0-2026-42804)

Vulnerability from cvelistv5 – Published: 2026-09-10 08:56 – Updated: 2026-09-10 15:01

Summary

A stack-based buffer overflow vulnerability exists in the Bosch Sensortec BHI360 SensorAPI(C-Library) in versions up to and including commit d6b200416a. The vulnerability is located within the FIFO parsing and debug logging subsystem inside the function bhi360_parse_debug_message() in bhi360_parse.c (lines 1852-1875). The parser trusts the first payload byte of a debug frame as the message length (msg_length) and copies that many bytes into a fixed-size 17-byte stack buffer (debug_msg) via memcpy without performing any bounds checking. A locally or physically positioned attacker (e.g., via a malicious sensor, counterfeit hardware module, or a Man-in-the-Middle on the communication bus) can exploit this vulnerability by injecting a crafted debug frame with a length byte exceeding 16. This corrupts adjacent stack data, including the saved return address. Furthermore, because the overflowed buffer is subsequently passed to a printf-style logging sink, the attacker can supply format string specifiers (e.g., %n) to execute arbitrary code on the host microcontroller/SoC or cause a reliable system crash (Denial of Service).
