Linux Distros Unpatched Vulnerability : CVE-2026-54874

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

QUIC ACK-only Packet Retention Can Cause Memory Exhaustion

Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...

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.
