Linux kernel

Ubuntu 26.10 is now available to download. The new release ships with GNOME 51 and the Linux 7.3 kernel, and introduces new window tiling features along with expanded Rust tooling for developers. Linux enthusiasts and open source watchers are sharing recaps of the changes and discussing which improvements stand out in the latest version of the popular distribution.

The Linux kernel project has removed its requirement that contributors disclose when they used AI tools in their code. Linus Torvalds said contributors must understand the code they submit, regardless of the tools they used to write it. The change has prompted discussion among developers about accountability and review standards as AI-assisted coding becomes routine.

The upcoming Ubuntu 26.10 release will include the Linux 7.3 kernel even before its official launch, according to reports from Heise. The new version also offers an optional desktop AI assistant called Myna. The combination of an unreleased kernel and built-in AI tooling is drawing attention from Linux users discussing the direction of the popular distribution.

A critical vulnerability in the Linux TCP/IP stack, tracked as CVE-2026-98432, has been disclosed with a CVSS score of 9.8. The flaw is described as a use-after-free bug in TCP handling that could allow attackers to remotely compromise affected systems. Engineers are discussing the technical details, severity ratings and the challenge of fixing memory-safety bugs in the kernel's networking code.

Linus Torvalds has reportedly merged his first patch series in which a large language model assisted with the work, according to LWN. The news has drawn attention across developer communities, with commenters debating what it signals about AI's growing role in Linux kernel development and whether tooling like this will become routine for kernel maintainers.

Anthropic's AI model has been credited with finding a vulnerability in the Linux kernel, tracked as CVE-2026-98432, which could allow attackers to gain remote root access to affected systems. Security outlet CSO Online reported the discovery, and the bug is drawing attention across searches in the UK, Germany, Russia and Japan as researchers assess its severity.

Linus Torvalds is now openly using AI in an experimental branch of the Linux kernel, under the name noref-filemap-read-with-llm. Reports say he uses Claude Code for tests and commit messages, framing it as speeding up monotonous work rather than replacing developers. Related AI news rounds also mention a four-person team that reverse-engineered Adobe technology.

Two unannounced Raspberry Pi models — a Zero 3W and a Pi 4 Model A — have been identified in Linux kernel device tree files, which typically list hardware before official release. The discovery suggests the Raspberry Pi Foundation is preparing new variants of its single-board computers, and hobbyists are speculating about specs, pricing and release dates.

A security discussion is underway after it was noted that Go programs enable Multipath TCP by default on Linux, which exposes them to the recently disclosed kernel vulnerability CVE-2026-98432. Developers are weighing the risk to Go-based network services and whether the default should be changed, with the Go team's announcements list cited as the reference point.

Ubuntu has released patched kernels addressing a critical flaw in the Linux TCP implementation, staging them in a testing area for 22.04 LTS and newer releases. The company says applying the kernel updates, rather than disabling Multipath TCP, is the right defense while wider testing continues.

Open Source consultancy Collabora has relocated its Mastodon account from floss.social to Fosstodon, telling existing followers they will carry over automatically. The company, which works on the Linux kernel, graphics, multimedia, machine learning and XR, says it will use the new account to share engineering blog posts, talks and software releases.

A batch of security stories is drawing attention: PHP vulnerabilities, SSL certificates secured with comically weak keys, and an accidental disclosure of a Linux kernel CVE. On a different note, Canonical is ramping up development of its immutable version of the Ubuntu desktop, which hopefully will not be limited to GNOME.

Linux kernel 7.2 has reached its end of life, meaning it will no longer receive bug fixes or security patches from developers. Users still running the series are advised to move to the Linux 7.3 kernel, which is now the maintained release. Free and open source software communities are sharing the announcement, reminding system administrators to update their installations promptly to stay protected.

A headline simply reading 'Linux 7.3' is circulating on a developer news aggregator, linking to an LWN article about the version. The current Linux kernel series is in the 6.x range, so any reference to 7.3 prompts debate over whether the kernel is jumping version numbers or the label is a mistake or joke.

Security researchers report that Claude AI was able to exploit a Linux kernel vulnerability to execute root commands without any user interaction. The finding has raised alarm in the cybersecurity community, as it demonstrates how AI agents could be leveraged to autonomously exploit system flaws, prompting renewed debate about the safety risks of granting AI tools deep system access.

Linus Torvalds has announced the first release candidate of Linux kernel 7.4, opening the testing period for the next version of the kernel. Release candidates let developers and testers try new features before the stable release, which typically follows after several weeks of candidates. Free and open-source software communities are circulating the announcement as testers begin downloading and reporting bugs on the new build.

The Linux Lite project has released version 8.2 of its beginner-friendly distribution, built on Ubuntu 26.04 LTS and shipping with the Linux 7.3 kernel. The update, reported by 9to5linux, is drawing attention in open-source communities as users consider upgrading to get the latest kernel features and long-term Ubuntu base.

Several Linux kernel security vulnerabilities were unintentionally disclosed on the public Linux Kernel Mailing List, meaning exploit details may have been visible before patches were ready. The incident has raised concerns among developers and security researchers about disclosure practices and whether fixes will land in time to protect systems running the kernel.

A critical vulnerability in the Linux kernel is drawing attention from security researchers and system administrators, with warnings that attackers could exploit it to gain remote control over affected servers. Administrators are urged to patch affected systems promptly, and discussion is focused on which kernel versions are vulnerable and how widely servers may be exposed.

Linus Torvalds says the Linux kernel is out of its stabilization phase and that AI-related contributions now follow a 'much healthier model'. He acknowledged machine-made patches still 'often get rewritten', suggesting AI-assisted code is entering the kernel process under closer human review rather than being accepted wholesale.

A new operating system project called AlpineBSD has been announced. It combines the NetBSD kernel with a userspace inspired by Alpine Linux, and states as a goal the use of as little AI-generated software as possible, with no LLM output included in the base system or main packages. The announcement is drawing attention from free software enthusiasts interested in alternatives that keep AI tooling out of core development.

A newly assigned vulnerability, CVE-2026-98432, describes a use-after-free flaw in the Linux kernel's IPv4 networking code. Use-after-free bugs in core network code are considered serious because they can potentially allow privilege escalation or remote code execution. Security researchers and Linux maintainers are expected to assess affected kernel versions and ship patches.
