CVE-2026-84782 is a reported OpenSSL DTLS handshake retransmission issue that may cause plaintext heap-memory disclosure or denial of service.
Defender checklist
- Inventory DTLS-dependent services, including embedded products.
- Confirm OpenSSL versions and follow vendor fixes.
- Reduce exposure of unpatched DTLS services and monitor handshake anomalies.
A vulnerable version is not proof of an incident. Establish exposure, patch supported products, and follow authoritative guidance.
