CVE-2026-84782

A flaw was found in OpenSSL. The Datagram Transport Layer Security DTLS retransmission mechanism fails to properly handle handshake message writes that are suspended before completion. A remote attacker could exploit this vulnerability during handshake message retransmission, causing OpenSSL to...

CVE-2026-84784 QUIC: Unbounded RETIRE_CONNECTION_ID Backlog

Issue summary: A malicious remote peer may flood the local QUIC stack with NEWCONNECTIONID frames by avoiding a limit check on how many connection IDs the remote QUIC stack can use. Impact summary: The local QUIC stack sends a RETIRECONNID frame for every NEWCONNECTIONID frame it receives. The...

CVE-2026-84784

The OpenSSL QUIC stack is vulnerable to a Denial of Service (DoS) attack due to a flaw in how it handles connection identifier (CID) retirement. A malicious remote peer can flood the local stack with NEW_CONNECTION_ID frames while withholding acknowledgments. Because the stack incorrectly retires...
