On the security front, the release adds support for ML-DSA, or Module-Lattice-Based Digital Signature Algorithm, a FIPS 204 standard approved by NIST designed to resist attacks from future quantum computers. The algorithm is initially being used for module signing, with broader kernel integration planned for future releases.
Linux 7.0 is expected to ship with Ubuntu 26.04 LTS later this month and is already available in rolling-release distributions.
Linux Kernel 7.0 Arrives with Rust Going Stable and Quantum-Proof Cryptography

Linux kernel 7.0 has been officially released, marking Rust as a stable part of the kernel toolchain after years of experimentation. The release also introduces self-healing XFS filesystems, post-quantum cryptographic signatures, and a new policy requiring human accountability for AI-generated code contributions.
A New Era for the Linux Kernel
Linus Torvalds released Linux kernel 7.0 on Sunday, April 12, 2026, closing out a turbulent release candidate cycle and opening a new major version series. While the version number is technically a routine rollover from 6.19, the release carries significant technical advances that will ripple across the entire open-source ecosystem.Rust Goes Permanent
The headline change is the graduation of Rust language support from experimental to officially stable. The decision to conclude the Rust experiment was made at the 2025 Linux Kernel Maintainers Summit, signalling that Rust is now a permanent part of the kernel toolchain. The move targets the memory-safety bugs that have long plagued C-based systems code, including buffer overflows, use-after-free errors, and null-pointer dereferences, which are structurally impossible in safe Rust.Self-Healing Filesystems and Quantum-Resistant Security
Kernel 7.0 introduces autonomous self-healing capabilities for the XFS filesystem through a new xfs_healer daemon managed by systemd. The system watches for metadata failures and input output errors in real time and triggers repairs automatically while the filesystem stays mounted, eliminating the need for downtime during data recovery.On the security front, the release adds support for ML-DSA, or Module-Lattice-Based Digital Signature Algorithm, a FIPS 204 standard approved by NIST designed to resist attacks from future quantum computers. The algorithm is initially being used for module signing, with broader kernel integration planned for future releases.
AI Code Gets Ground Rules
The kernel's development process has also adapted to the rise of AI tools. A new policy finalised this week requires contributors to use an Assisted-by tag for any AI-generated code, placing full legal and technical responsibility on the human submitter. The move follows a period where AI-generated bug reports shifted from low-quality noise to legitimate, actionable findings, contributing to an above-average commit count throughout the release cycle.Linux 7.0 is expected to ship with Ubuntu 26.04 LTS later this month and is already available in rolling-release distributions.
