CVE-2025-11617

A missing validation check in FreeRTOS-Plus-TCP's IPv6 packet processing code can lead to an out-of-bounds read when receiving a IPv6 packet with incorrect payload lengths in the packet header. This issue only affects applications using IPv6. We recommend users upgrade to the latest version and ensure any forked or derivative code is patched to incorporate the new fixes.

Summary		(es) Una comprobación de validación faltante en el código de procesamiento de paquetes IPv6 de FreeRTOS-Plus-TCP puede conducir a una lectura fuera de límites al recibir un paquete IPv6 con longitudes de carga útil incorrectas en la cabecera del paquete. Este problema solo afecta a las aplicaciones que utilizan IPv6. Recomendamos a los usuarios actualizar a la última versión y asegurarse de que cualquier código bifurcado o derivado sea parcheado para incorporar las nuevas correcciones.
