Red Hat has released RHEL 10.3 and the RHEL 9.9 update, shipping with Linux kernel 6.12.

This release introduces "sealed images" for boot integrity and moves the AI-focused MCP server to general availability.

Developers get access to updated toolchains, including GCC 16.2.1, Go 1.27, Rust 1.97, 11, along with simplified in-place migration paths via the Leapp tool.

Safety at startup

An important addition is the so-called "sealed" system images. This feature checks whether the software has been modified without permission every time the computer starts. If the system detects that a file has been changed, it can stop its operation to prevent malicious programs from running.

Systems management with artificial intelligence

Red Hat has now made a tool available to all users that allows artificial intelligence programs to connect to the system. Administrators can use digital assistants to check the status of their computers or automate tasks. In addition, the system now allows enterprises to run their own artificial intelligence models locally, via OpenShift AI.

Tools and software upgrades

Developers have access to newer versions of tools, such as the GCC 16 set, which includes the GCC 16.2.1 compiler and the GNU Binutils 2.46 tools. At the same time, many popular languages and platforms have been updated, such as Go 1.27, Rust 1.97, .NET 11, Node.js 26, and PHP 8.4. The Valkey database has also been upgraded to version 8.1.

Preparing for future threats

Red Hat has improved its encryption systems to prepare for future security challenges posed by supercomputers (quantum computers). Finally, the company announced that easy upgrades are now supported for those with older versions, allowing users to move from RHEL 9.9 to 10.3, or from RHEL 8.10 to 9.9, using the Leapp tool.
