CVE-2026-55953
The Erlang/OTP ssl TLS 1.2 and earlier and DTLS client does not verify that the cipher suite selected by the server in ServerHello was among the suites offered by the client in ClientHello. The client-side tlshandshake:hello/5 handler validates the negotiated protocol version and the downgrade...
CVE-2026-55953 TLS 1.2 and DTLS client accepts unoffered anonymous cipher suite, bypassing server authentication
The Erlang/OTP ssl TLS 1.2 and earlier and DTLS client does not verify that the cipher suite selected by the server in ServerHello was among the suites offered by the client in ClientHello. The client-side tlshandshake:hello/5 handler validates the negotiated protocol version and the downgrade...
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 ...
PT-2026-39574
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...
SUSE CVE-2026-27017
uTLS is a fork of crypto/tls, created to customize ClientHello for fingerprinting resistance while still using it for the handshake. Versions 1.6.0 through 1.8.0 contain a fingerprint mismatch with Chrome when using GREASE ECH, related to cipher suite selection. When Chrome selects the preferred...

CVE-2026-27017
CVE-2026-27017 affects the uTLS fork of crypto/tls ( Versions 1.6.0–1.8.0 ) with GREASE ECH, causing a fingerprint mismatch with Chrome due to inconsistent cipher-suite selection between the outer ClientHello and ECH. Specifically, uTLS hardcodes AES for the outer cipher suite while randomly sele...
