Oracle Linux 10 is now generally available for 64-bit Intel and AMD (x86_64) and 64-bit Arm (aarch64) platforms. Oracle Linux 10 delivers cloud-scale business agility along with strong security and outstanding performance for demanding workloads. Key features include the latest cryptographic capabilities, enhanced developer tools, and innovations to strengthen infrastructure resilience, enabling enterprises to build and run applications faster and more securely in distributed and multi-cloud environments.

Following the release of Unbreakable Enterprise Kernel 8 (UEK 8), optimized on Oracle's latest long-term support kernel, Oracle Linux 10 includes UEK 8.1. This reflects Oracle's ongoing commitment to delivering industry-leading performance and stability. Oracle Linux 10 also includes an updated Red Hat Compatible Kernel and maintains 100% application binary compatibility with Red Hat Enterprise Linux 10. Keeping its promise to make Linux open and freely available to everyone, Oracle, as a founding member of the Open Enterprise Linux Association (OpenELA), continues to contribute to, maintain, and support enterprise Linux source code.

☑️ Key Features of Oracle Linux 10

A High-Performance Kernel at the Core of Oracle Linux 10

Unbreakable Enterprise Kernel 8 (UEK 8), the default kernel of Oracle Linux 10, is designed for data-centric and compute-intensive workloads. It includes advanced capabilities across memory management, file systems, and networking, with contributions from both Oracle and the upstream community. Customers around the world run their systems on Oracle Linux and UEK in mission-critical distributed environments, including Oracle Database, Oracle Exadata, and Oracle Cloud Infrastructure (OCI). Across a variety of industries, including finance, the public sector, and education, Oracle Linux is trusted as the foundation for a wide range of applications, including OLTP, large-scale data analytics, and AI/ML workloads.

Proactively Respond to Threats and Operate Reliably with Zero-Downtime Patching

Oracle Linux 10 supports Ksplice zero-downtime patching, provided with Oracle Linux Premier Support. This allows critical updates to the kernel and user space (including glibc and OpenSSL) to be applied without rebooting the system. Automated live patching technology applies critical updates within seconds, keeping systems secure and up to date without interrupting running applications. Oracle Ksplice avoids patch-related reboots and helps improve operational efficiency and reduce costs across on-premises and cloud environments.

Enterprise-Grade Security Capabilities for Future Security Challenges

For enterprise environments that require strong authentication and zero trust principles, Oracle Linux 10 has significantly improved OpenSSH security and usability. Highlights include keystroke obfuscation to prevent side-channel attacks, stronger restrictions on key forwarding and usage, and automatic termination of inactive SSH channels. The SSH daemon has been redesigned to separate connection handling from session management, reducing the attack surface. The FIDO-based authentication system provides a more secure environment through improved hardware key handling and protection against credential overwriting.

To support new cryptographic standards and protect data, Oracle Linux 10 introduces Post-Quantum Cryptography (PQC) as a Technology Preview. These are next-generation algorithms designed to prepare for quantum computing-based attacks, and the pkeyutl utility supports encapsulation and decapsulation operations, including the newly defined ML-KEM (based on FIPS 203) algorithm.

※ Note: The Post-Quantum Cryptography (PQC) Technology Preview is not intended for use in production environments and is provided for testing and development purposes only.

Enhanced Development Tools for Superior Performance and Scalable Innovation

Oracle Linux 10 delivers upgrades across the tools developers use every day, including the latest compiler toolchains and improved observability. In addition to C, C++, and OpenMP-related features, GCC provides security hardening options, improved diagnostics, and performance optimizations. Valkey, a high-performance in-memory key-value store that fully replaces Redis while offering full compatibility and scalability, has also been introduced. Most applications can use existing Redis configurations and data as is, without modification. In addition, Grafana offers a refreshed UI and enhanced user access control, and the latest APIs for .NET developers expand networking and data access capabilities and support a variety of platforms and architectures.

Optimized Programming Capabilities for Next-Generation Applications

Oracle Linux 10 provides updates to improve performance and increase development efficiency across major programming languages and database technologies. Python runs faster thanks to compiler optimization settings, performance improvements through inlined comprehensions, and more readable type syntax. In addition, Perl, Node.js, MySQL, and others have been upgraded with improvements in security, performance, and developer productivity.
