CVE-2026-1677 net: TLS 1.2 connections allowed on TLS 1.3 sockets

Zephyr sockets created with IPPROTOTLS13 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 mbedtlssslconfmintlsversion. The ClientHello advertises both versions and the peer can...

CVE-2026-1677

CVE-2026-1677 concerns Zephyr: sockets created with IPPROTO_TLS_1_3 may still negotiate TLS 1.2 when both TLS versions are enabled, because socket‑level protocol selection isn’t propagated to mbedTLS (e.g., via mbedtls_ssl_conf_min_tls_version). The ClientHello can advertise both TLS 1.2 and TLS ...
