Oracle Linux 10 Now Generally Available
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 robust security and exceptional performance for business agility and demanding workloads at cloud scale. Key features include modernized cryptographic capabilities, advancements in developer tooling, and innovations for resilient infrastructure. These enhancements enable organizations to build and run applications faster and more securely across distributed and multicloud environments.
Following the recent release of the Unbreakable Enterprise Kernel 8 (UEK 8)—Oracle's optimized kernel based on the latest upstream long-term stable kernel—Oracle Linux 10 includes UEK 8.1. This underscores Oracle's continued focus on providing industry-leading performance and stability that organizations rely on. In addition, Oracle Linux 10 includes an updated Red Hat Compatible Kernel. Oracle Linux 10 maintains 100% application binary compatibility with Red Hat Enterprise Linux 10 and delivers on Oracle's commitment to keeping Linux open and free for everyone. As a founding member of the Open Enterprise Linux Association (OpenELA), Oracle continues to contribute, maintain, and support freely available Enterprise Linux source code.
The highly performant kernel at the core of Oracle Linux 10
The newest Oracle Linux kernel, the Unbreakable Enterprise Kernel 8 (UEK 8), is purpose-built for data-heavy and compute-intensive workloads. The default kernel in Oracle Linux 10, UEK 8 delivers state-of-the-art innovations in memory management, file systems, and networking. These enhancements, contributed by both Oracle and the upstream Linux community, provide the performance and reliability essential to today's enterprises. Customers worldwide rely on Oracle Linux featuring UEK to power mission-critical, distributed deployments, spanning Oracle Database, Oracle Exadata, and Oracle Cloud Infrastructure (OCI). Trusted by organizations in finance, government, education, and beyond, Oracle Linux serves as the foundation for a broad range of applications, from OLTP and large-scale data analytics to AI/ML workloads.
Stay ahead of threats: Patch without downtime, operate confidently
Oracle Ksplice zero-downtime patching, available with Oracle Linux Premier Support, is supported on Oracle Linux 10. It enables critical kernel and user space updates, including glibc and OpenSSL, without requiring system reboots. This automated live-patching technology delivers critical updates in seconds, helping systems stay continuously secure and up to date without disrupting running applications. With Oracle Ksplice, avoid business interruptions caused by forced reboots during patching, leading to cost savings and improved operational efficiency across on-premises and cloud deployments.
Enterprise-grade security for today’s infrastructure—and tomorrow’s challenges
For enterprise environments, where strong authentication and zero-trust principles are critical, Oracle Linux 10 presents a significant upgrade to OpenSSH with a range of security and usability improvements. These enhancements include keystroke obfuscation to help prevent side-channel attacks, expanded restrictions on key forwarding and usage to enhance credential security, and automatic closure of inactive SSH channels. Additionally, the SSH daemon has been rearchitected to separate connection handling from session management, helping reduce the attack surface. Systems using FIDO-based authentication can benefit from improved hardware key handling and enhanced safeguards against credential overwrites.
To further help organizations safeguard data and align with emerging cryptographic standards, Oracle Linux 10 introduces post-quantum cryptography (PQC) as a technology preview. This provides a set of next-generation algorithms designed to help resist quantum attacks. Among the expanded cryptographic tooling, the pkeyutl utility now supports encapsulation and decapsulation operations, including the new PQC algorithm ML-KEM (as defined in NIST’s FIPS 203).
Note: The post-quantum cryptography (PQC) technology preview is not intended for use in production environments. This technology preview is for testing and development purposes only.
Enhanced developer tooling for superior performance and scalable innovation
From modernized compiler toolchains to refined observability, Oracle Linux 10 brings advancements to the tools developers rely on daily. GCC updates deliver a range of C, C++, and OpenMP features alongside hardened security options, improved diagnostic capabilities, and performance-focused optimizations. Oracle Linux 10 introduces Valkey, a high-performance, in-memory key-value store that replaces Redis while maintaining full compatibility and greater scalability. The transition is transparent to most applications, with existing Redis configurations and data working without modification. Additionally, Grafana introduces a refreshed UI and strengthened user access controls. For developers using .NET, the latest version adds new APIs for networking and data access, along with expanded support across diverse platforms and architectures.
Optimized programming capabilities to fuel next-generation applications
Oracle Linux 10 delivers enhancements across key programming languages and database technologies, increasing performance and streamlining day-to-day development. Updates to Python bring faster execution through optimized compiler settings, inlined comprehensions for significantly improved performance, and updated typing syntax for better code readability. Other upgraded components include Perl, Node.js, and MySQL, each bringing enhancements that increase performance, operational security, and developer productivity.
