    High [CVE-2026-55952] Denial of Service in TLS 1.3 session ticket handling

    CVE-2026-55952Source published Source updated

    The Erlang/OTP ssl application does not validate that the PSK identity list and binder list carried in a TLS 1.3 ClientHello pre-shared key extension have equal length before passing them to the session ticket handler. In tls_handshake_1_3:handle_pre_shared_key/3, an OfferedPreSharedKeys record with a mismatched number of identities and binders is forwarded directly to tls_server_session_ticket:use/4, which crashes the session ticket handler process. An unauthenticated remote attacker can send a single crafted ClientHello to a TLS 1.3 server with session tickets enabled (stateful or stateless mode) and permanently disrupt session ticket handling on that listener. New TLS 1.3 handshakes complete but subsequently crash when the server attempts to issue a session ticket, effectively making…

    Mitigation guidance
    • Restarting the ssl application restores TLS 1.3 functionality after a crash. TLS 1.2 connections are not affected. Disabling TLS 1.3 session tickets (stateful and stateless) eliminates the attack surface.
