CVE-2026-54874

OpenSSL is vulnerable to a remote memory exhaustion Denial of Service risk in its DTLS component (CWE-405). While a handshake is in progress, a peer may move to a future epoch before the local endpoint catches up, causing OpenSSL to buffer early records. Instead of buffering only the necessary by...

CVE-2026-59646

A flaw was found in Bouncy Castle for Java. The DTLS Datagram Transport Layer Security handshake reassembler allocates buffers based on an unchecked 24-bit length value. A remote attacker could exploit this vulnerability by sending a specially crafted DTLS handshake message, leading to excessive...
