Vulnerability Title
net: TLS 1.2 connections allowed on TLS 1.3 sockets
Vulnerability Description
Zephyr sockets created with `IPPROTO_TLS_1_3` can still negotiate a TLS 1.2 connection when both TLS versions are enabled in Kconfig, because the socket-level protocol selection is not propagated to mbedTLS (e.g. via `mbedtls_ssl_conf_min_tls_version`). The ClientHello advertises both versions and the peer can establish TLS 1.2, so applications that assumed `IPPROTO_TLS_1_3` enforces TLS 1.3 may silently use TLS 1.2 and remain exposed to TLS 1.2-specific weaknesses. As a workaround, the `TLS_CIPHERSUITE_LIST` socket option can be restricted to TLS 1.3-only cipher suites.

Vulnerability Title
Zephyr 安全漏洞
Vulnerability Description
Zephyr是Zephyr开源的一个可扩展的实时操作系统 (RTOS)。 Zephyr存在安全漏洞,该漏洞源于使用IPPROTO_TLS_1_3创建的套接字在启用两种TLS版本时仍可协商TLS 1.2连接,因为套接字级别的协议选择未传播到mbedTLS,可能导致应用程序静默使用TLS 1.2并暴露于TLS 1.2特定弱点。
