CVE-2025-55081

In Eclipse Foundation NextX Duo before 6.4.4, a module of ThreadX, the _nx_secure_tls_process_clienthello() function was missing length verification of certain SSL/TLS client hello message: the ciphersuite length and compression method length. In case of an attacker-crafted message with values outside of the expected range, it could cause an out-of-bound read.

Summary		(es) En Eclipse Foundation NextX Duo anterior a 6.4.4, un módulo de ThreadX, la función _nx_secure_tls_process_clienthello() carecía de verificación de longitud de ciertos mensajes 'client hello' SSL/TLS: la longitud de la suite de cifrado y la longitud del método de compresión. En caso de un mensaje elaborado por un atacante con valores fuera del rango esperado, podría causar una lectura fuera de límites.
