CVE-2025-55081Potential out of bound read in _nx_secure_tls_process_clienthello()

Descripción

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.
