CVE-2026-54874 Excessive Memory Use Buffering DTLS Records for a Future Epoch

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...

CVE-2026-54874

CVE-2026-54874 is a memory amplification vulnerability in OpenSSL's DTLS implementation. When a handshake is in progress, OpenSSL buffers records belonging to a future epoch by retaining the full ~16 KB read buffer per record rather than only the actual record bytes. Up to 100 records per connect...
