CVE-2026-54874

A flaw was found in OpenSSL. Receiving a DTLS Datagram Transport Layer Security record for a future epoch while a handshake is in progress causes OpenSSL to buffer an excessive amount of memory. This allows a peer to cause memory exhaustion, eventually resulting in a denial of service, using a...

EUVD-2026-65481

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large...

OpenSSL 1.1.1 < 1.1.1zi Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.1.1zi. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.1zi advisory. - Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more...
