Notes

Title of the patch: Security update for micropython

Description of the patch: This update for micropython fixes the following issues: Changes in micropython: - Build with mbedtls-3.6.5 instead of bundled 3.6.2 to fix CVE-2025-59438 Version 1.26.0: * Added machine.I2CTarget for creating I2C target devices on multiple ports. * New MCU support: STM32N6xx (800 MHz, ML accel) & ESP32-C2 (WiFi + BLE). * Major float accuracy boost (~28% → ~98%), constant folding in compiler. * Optimized native/Viper emitters; reduced heap use for slices. * Time functions standardized (1970–2099); new boards across ESP32, SAMD, STM32, Zephyr. * ESP32: ESP-IDF 5.4.2, flash auto-detect, PCNT class, LAN8670 PHY. * RP2: compressed errors, better lightsleep, hard IRQ timers. * Zephyr v4.0.0: PWM, SoftI2C/SPI, BLE runtime services, boot.py/main.py support. * mpremote adds fs tree, improved df, portable config paths. * Updated lwIP, LittleFS, libhydrogen, stm32lib; expanded hardware/CI tests.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
