On the first DTLS ClientHello, the parser copies a device-claimed session_id length and validates the ciphersuite-list length against the total record length instead of the remaining bytes. An unauthenticated peer drives an OOB source read of up to 255 bytes, and those bytes are echoed verbatim into the outgoing ServerHello, disclosing adjacent process memory over the network. The crash variant fires on the first packet.
