GhostESP v2.2-pre1

The ESP-IDF-native wireless security platform for ESP32. Deep Wi-Fi and BLE assessment, research-grade capture and export, and a real app ecosystem. Built directly on Espressif's ESP-IDF rather than through the Arduino core, so new silicon and radio features land first and there is no abstraction...

CVE-2026-45329

ESF-IDF is the Espressif Internet of Things IOT Development Framework. In versions 5.5.4 and 6.0, several ESP-TEE secure-service wrappers in espsecureservices.c and espsecureservicesiram.c validated only some of the caller-supplied pointer arguments, leaving input pointer arguments unchecked...
