Latest Linux and open source news from around the web
Johannes Schindelin has posted a detailed summary of the discussions held at the 2026 Git Contributors' Summit. Topics covered include Git 3.0, security process, documentation, the pluggable object database, use of LLMs, and more.

The F-Droid project has announced the release of F-Droid 2.0, which is a complete redesign of the official app. Notable changes in the release include making it easier to discover and install applications, more useful app categories, improved search, and much more. For more than a decade, F-Droid has helped people discover and install free and open source Android apps. F-Droid 2.0 builds on that foundation with a modern interface, better app discovery, improved search, and a simpler experience that works well, whether you're new to F-Droid or have been using it for years. This isn't just a visual refresh. The user experience was redesigned to integrate smoothly with current Android patterns, like Material Design, while keeping familiar F-Droid interactions in place. Key components were reworked and rewritten using Kotlin Compose, the standard toolkit these days, creating a foundation that will help us deliver improvements more quickly in the years ahead.
Sudheendra Raghav Neela, a member of a group of researchers from Graz University of Technology, has announced the release of research into file-notification attacks that would allow spying on user activity on Android, Linux, macOS, and Windows. The group has published a paper with details on the research as well as a web site with demonstrations of the vulnerabilities. On Linux, an attacker can use inotifywatch to monitor a directory to conduct an inter-keystroke timing attack—even if they do not have read access to the files within a directory. The group also discovered a method to conduct a UI-redress attack (or "clickjacking" attack) on KDE 5 and KDE 6 by monitoring /usr/bin/pkexec to detect when Polkit spawns an authentication prompt. An attacker could draw a fake password window on top of the real window to collect a user's credentials. Both of these flaws are still present today, though the Linux kernel did partially mitigate the issue with a fix that was included in the 5.10.248
Many of the transmissions sent over the radio spectrum can be decoded with a relatively cheap hardware dongle. Thomas Eckert presented at RustConf 2026 in Montreal about his hobby: decoding radio transmissions with Rust. In his presentation, he covered all of the math necessary to get started with software-defined radio, and gave demonstrations of listening to AM and FM radio, as well as decoding transmissions from aircraft transponders. His slides and example code are available on GitHub.
After a two-year hiatus, LWN's Jonathan Corbet presented an updated edition of his Kernel Report at the Kernel Recipes conference. Corbet looked at what is happening in the kernel community, how it's dealing with a period of accelerated change, and where things might go in the future. Video of the talk is available on YouTube for those who'd like to tune in.

Inside this week's LWN.net Weekly Edition: Front: Git 2.56; gccrs; NetBSD and compat_linux; io_uring; Desktop UX. Briefs: WordPress vulnerability; Radicle vulnerability; Systemtap 5.6; GNOME 51; Systemd v262; Quotes; ... Announcements: Newsletters, conferences, security updates, patches, and more.
Scott Jenson has been working on user interfaces (UIs) and user experience (UX) for many years at Apple, Google, and other companies. Now, he's trying to convince open-source projects to experiment more and drive the desktop beyond the age-old "windows, icons, menus, pointer" (WIMP) model. At Akademy 2026, KDE's annual developer conference, he shared his complaints and ideas in a talk aimed at convincing those in attendance to take the lead on desktop design.
Systemd v262 has been released. Some of the notable new features include the ability to build systemd as a single statically linked binary for small containers, support for the kernel coredump socket protocol introduced with Linux 6.17, addition of OpenSSL 4 support, and many other changes. See the release notes for a full list of changes.
The Radicle peer-to-peer code-collaboration project has disclosed two critical vulnerabilities in the network protocol used by Radicle nodes. The first flaw is that the network protocol used by Radicle "does not give the confidentiality it was expected to give", which allows anyone who can observe the network between two nodes to read the data exchanged. The second is that peer authentication is broken and allows impersonation, so an attacker can spoof their Node ID and read private repositories they should not be able to read. In practice, the two flaws are most useful when they can be exploited together: an attacker on the path sees the Node IDs at both ends of a connection, and both are normally on the allow-list. That attacker can read whatever is exchanged while they watch, and can then use a Node ID they saw to fetch the whole repository on demand. The realistic threat is anyone on the path between your node and node it syncs with, and no setting or allow-list protects against th
A critical vulnerability has been discovered in WordPress's get_page_template() function for page-template resolution that could allow remote-code execution (RCE) by an unauthenticated attacker, in some limited circumstances. The project has provided an update for the most recent branch of WordPress, as well as backports of the fix for branches back to 4.7. See the vulnerability for the conditions required for an RCE attack to be successful. The vulnerability also affects the ClassicPress fork of WordPress, though a security update has not been provided for that project yet. LWN covered ClassicPress in 2024. Users of either content-management system should update soon.

Pierre-Emmanuel Patry and Arthur Cohen gave a talk at RustConf 2026 on the status of the Rust frontend for GCC (gccrs), with a particular eye toward the goal of compiling the Linux kernel. Patry gave a follow-up talk for a more kernel-focused audience at Kangrejos the next week, which Cohen could not attend. The gccrs project is making good progress overall, but it will still be some time until the compiler is usable.
