Oracle Linux 9.7 Debuts with PQC Security, Updated UEK/RHCK Kernels

Oracle Linux 9.7 is now globally available, continuing Oracle’s alignment with Red Hat Enterprise Linux by maintaining full application binary compatibility while offering its own enhancements through the Unbreakable Enterprise Kernel.

The release highlight is an expanded support for post-quantum cryptographic algorithms. System-wide crypto-policies now prioritize hybrid ML-KEM and pure ML-DSA, and OpenSSL has been updated to include ML-KEM, ML-DSA, and SLH-DSA.

QUIC transport support has also been added, improving performance for latency-sensitive applications and boosting the overall efficiency of encrypted connections.
