  3. CVE-2026-25507
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.2, 5.4.3, 5.3.4, 5.2.6, and 5.1.6, a use-after-free vulnerability was reported in the BLE provisioning transport (protocomm_ble) layer. The issue can be triggered by a remote BLE client while the device is in provisioning mode. The vulnerability occurred when provisioning was stopped with keep_ble_on = true. In this configuration, internal protocomm_ble state and GATT metadata were freed while the BLE stack and GATT services remained active. Subsequent BLE read or write callbacks dereferenced freed memory, allowing a connected or newly connected client to trigger invalid memory acces. This issue has been patched in versions 5.5.3, 5.4.4, 5.3.5, 5.2.7, and 5.1.7.

Summary
  • (es) ESF-IDF es el Framework de Desarrollo de Internet de las Cosas (IoT) de Espressif. En las versiones 5.5.2, 5.4.3, 5.3.4, 5.2.6 y 5.1.6, se informó una vulnerabilidad de uso después de liberación en la capa de transporte de aprovisionamiento BLE (protocomm_ble). El problema puede ser activado por un cliente BLE remoto mientras el dispositivo está en modo de aprovisionamiento. La vulnerabilidad ocurrió cuando el aprovisionamiento se detuvo con keep_ble_on = true. En esta configuración, el estado interno de protocomm_ble y los metadatos GATT fueron liberados mientras la pila BLE y los servicios GATT permanecieron activos. Las devoluciones de llamada de lectura o escritura BLE posteriores desreferenciaron memoria liberada, permitiendo a un cliente conectado o recién conectado activar un acceso a memoria inválido. Este problema ha sido parcheado en las versiones 5.5.3, 5.4.4, 5.3.5, 5.2.7 y 5.1.7.
