The F-Droid project has announcedthe release of F-Droid2.0, which is a complete redesign of the officialapp. Notable changes in the release include making it easier to discover andinstall applications, more useful app categories, improved search, andmuch more.

Sudheendra Raghav Neela, a member of a group of researchers from Graz University of Technology, has announced therelease of research into file-notification attacks that would allow spying onuser activity on Android, Linux, macOS, and Windows. The group has published a paper withdetails on the research as well as a web sitewith demonstrations of the vulnerabilities.On Linux, an attacker can use inotifywatch tomonitor a directory to conduct an inter-keystroke timing attack-even ifthey do not have read access to the files within a directory. The group alsodiscovered a method to conduct a UI-redressattack (or "clickjacking" attack) onKDE5 and KDE6 by monitoring /usr/bin/pkexec to detect when Polkit spawns an authenticationprompt. An attacker could draw a fake password window on top of the real windowto collect a user's credentials.Both of these flaws are still present today,though the Linux kernel did partially mitigate the issue with afix that was included in the 5.10.248, 5.15.198, 6.1.160, 6.6.120, 6.12.65,and 6.18.3 kernels shipped in January. See the web site for more information anda mitigation to prevent password-prompt windows from losing focus.

Many of the transmissions sent over the radio spectrum canbe decoded with a relatively cheap hardware dongle. Thomas Eckert presented atRustConf 2026 in Montreal about his hobby:decoding radio transmissions with Rust.In his presentation, hecovered all of the math necessary to get started withsoftware-defined radio,and gave demonstrations of listening to AM and FM radio, as well as decodingtransmissions fromaircraft transponders. His slides and example code areavailable on GitHub.

After a two-year hiatus, LWN's Jonathan Corbet presented an updated editionof his KernelReport at the KernelRecipes conference. Corbet looked at what is happening in the kernelcommunity, how it's dealing with a period of accelerated change, and wherethings might go in the future. Video of the talk isavailable on YouTube for those who'd like to tune in.

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 convinceopen-source projects to experiment more and drive the desktop beyond the age-old "windows, icons, menus,pointer" (WIMP) model. At Akademy2026, KDE's annual developerconference, he shared his complaints and ideas in a talk aimedat convincing those in attendance to take the lead on desktop design.

Systemd v262 has been released. Some of the notable new features include theability to build systemd as a single statically linked binary for smallcontainers, support for the kernel coredump socket protocol introduced withLinux6.17, addition of OpenSSL4 support, and many other changes. Seethe releasenotes for a full list of changes.

The Radicle peer-to-peercode-collaboration project has disclosedtwo critical vulnerabilities in the network protocol used by Radiclenodes. The first flaw is that the network protocol used by Radicle "does notgive the confidentiality it was expected to give", which allows anyone whocan observe the network between two nodes to read the data exchanged. The secondis that peer authentication is broken and allows impersonation, so an attackercan spoof their Node ID and read private repositories they should not be able toread.

A criticalvulnerability 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 projecthas provided an update for the most recent branch of WordPress, as well asbackports of the fix for branches back to 4.7. See thevulnerability report for the conditions required for an RCE attack to be successful.The vulnerability alsoaffects the ClassicPress fork ofWordPress, though a security update has not been provided for that projectyet. LWN covered ClassicPress in2024. Users of either content-management system should update soon.

Pierre-Emmanuel Patry and Arthur Cohen gave a talk atRustConf2026 on thestatus of the Rust frontend for GCC (gccrs), with a particular eye toward thegoal ofcompiling the Linux kernel. Patry gave a follow-up talk for a morekernel-focused audience atKangrejos the next week, which Cohen could not attend. Thegccrs project ismaking good progress overall, but it will still be some time until the compileris usable.

The open-source consulting firm Igalia has put out anannouncement celebrating 25 years of working on upstream FOSS projectsfor its clients. The list of projects the company has worked on is rathereye-opening: WebKit, mobile-browser rendering (on Maemo, Moblin, MeeGo, andTizen), the Linux kernel (CPU and GPU scheduling), 3D graphics drivers, theOrca screen reader, GStreamer, and lots more. Beyond that, the company, which is aworker-owned cooperative, does its work in ways that benefit the communityas well as its clients:

Greg Kroah-Hartman has released the 7.2.7,6.18.53, and 6.12.111 stable kernels. As is usual these days, they arequite large; also no surprise is that they provide many important fixesthroughout the kernel tree. Users of those kernels are advised to update.

NetBSD has long had support forrunning Linux binaries via its kernel-level compat_linuxfeature, but test coverage for it was less complete than some mighthope. In order to provide better testing for compat_linux,Google Summer of Code (GSoC) participant Henrique Brito opted to workon enabling the Linux TestProject (LTP) test suite to compile and run on NetBSD. At EuroBSDCon2026, Brito'smentor, Stephen Borrill, provided a report on the project, and thestatus of LTP on NetBSD. The work has already resulted in some minorfixes, and a good list of additional problems to solve.

Linus Torvalds has released the 7.3-rc4kernel prepatch. It is, unsurprisingly at this point, large: "We all know the drill by now: 'it's big, yadda yadda'".

The Git source-code management system isat the core of development processes worldwide, so changes, especiallyincompatible changes, are of great interest to the developers involved.The Git 2.56 release, which can be expected around the end of September, iscurrently available in release-candidate form. Itis not the most earth-shaking of releases, but the one that follows, whichmight be the long-awaited Git 3.0, may well be.

Version 5.6 of the Systemtap tracing tool has been released.

Security updates have been issued by AlmaLinux (.NET 10.0, coreutils, kernel, libevent, libsoup3, microcode_ctl, perl-Net-DNS, postgresql18, postgresql:16, postgresql:18, tomcat, and unbound), Debian (bind9, chromium, libapache2-mod-auth-openidc, nginx, xz-utils, and zip), Fedora (chromium, freeipmi, GitPython, gnatcoll, nodejs-undici, parted, python-django5, and sblim-cmpi-base), Mageia (imagemagick and python-starlette), Oracle (.NET 10.0, .NET 8.0, .NET 9.0, coreutils, corosync, firewalld, kernel, libevent, libsoup, microcode_ctl, nginx:1.24, perl, perl:5.32, postgresql:16, postgresql:18, redis, rsync, rsyslog, tesseract, and unbound), Red Hat (vim), SUSE (alsa, chirp, chromium, cjose, cups, discount, firefox, gh, glibc, gvfs, jq, kernel, libcjose-devel, libmbedcrypto7, libpcap, mbedtls-2, netcdf, nodejs18, openai-codex, openvpn, pcre2, perl-net-dns, sngrep, tiff, and znc), and Ubuntu (bison, bubblewrap, and gst-plugins-good1.0).

The io_uringsubsystem is all about asynchronous execution; applications count on itto not block - unless explicitly requested to. Within io_uring, maintainingthe "never blocks" guarantee has sometimes been a challenge, given thatmany paths in the kernel were never designed for asynchronous execution.This problem has been worked around, but at a significant cost toperformance. Now, io_uring maintainer Jens Axboe has posted an RFC patch setwith a somewhat radical (and potentially scary) solution to the problem.

Version 51 of the GNOME desktopenvironment has been released. The list of changes includes a number ofperformance improvements, offline data and better transit information inthe Maps application, a new interface for the file previewer, and more.

Security updates have been issued by AlmaLinux (.NET 10.0, .NET 8.0, .NET 9.0, corosync, firewalld, kernel, kernel-rt, libevent, libsoup, microcode_ctl, nginx:1.26, python-lxml, rsyslog, tesseract, and unbound), Debian (firefox-esr, mkvtoolnix, thunderbird, and tor), Fedora (open62541, php-pecl-mongodb2, python-django6, python-jwcrypto, and roundcubemail), Mageia (aom, cockpit, libgd, packagekit, and python-h2), Red Hat (corosync, delve, git-lfs, grafana-pcp, gstreamer1-plugins-base, libvirt, opentelemetry-collector, and rhc-worker-playbook), Slackware (mozilla-firefox and mozilla-thunderbird), SUSE (acl, attr, alloy, ansible-core, clamav, containerized-data-importer, corosync, cups, distribution, glibc, google-cloud-sap-agent, govulncheck-vulndb, gvfs, helm, jq, kbd, kubernetes1.34-apiserver, kubernetes1.35-apiserver, lcms2, libcupsfilters, liblzmasdk26, libzypp, zypper, mistral-vibe, opensc, openvpn, pcre2, python-jwcrypto, tomcat, tomcat10, and tomcat11), and Ubuntu (guix, libheif, perl, python-cryptography, sqlite3, and valkey).

At the 2026 edition of FOSSY, RomeoSolano gave a fast-paced, humorous presentation on what could have been arather boring topic: server encryption. There are a number of threats thatwe face in today's world, from criminals, government overreach, espionage,and more, that can be thwarted with encryption. But encrypting data on asystem that may live elsewhere, without any access to its keyboard at boottime, is rather more difficult than encrypting the disk of a laptop.Solano described the problems and gave a tour of some of the solutions inthe talk.

The scheduling of block I/O requests has longbeen a challenge for operating-system kernels. For many years, theperformance characteristics of rotating drives meant that puttingconsiderable resources into request ordering was worthwhile. In a worldwith fast, solid-state drives, scheduling is more concerned with enforcingfairness between competing users while being fast enough to keep up withdrives that can perform millions of I/Ooperations per second. The blk-iocost I/Ocontroller was designed for the solid-state world and generally performswell, but there is always a desire to do better. This patchseries from Tao Cui aims to make blk-iocost more flexible by enablingthe loading of a BPF program to make cost decisions.

Padraig Brady has announcedGNU Core Utilities (coreutils) version 9.12. "There have been 288 commits by16 people in the 21 weeks since 9.11". New features include an -Aoption for unamewhich labels all output, as well as adding awareness of the failfs and nullfs filesystem types to statand tail.There are many bug fixes in this release as well, including one for a bug "presentin 'the beginning'" that caused some utilities to fail when traversinghierarchies if files are being removed in parallel.

What is it like to be a Debian Project Leader (DPL), or a former one?According to Andreas Tille, who stepped down this year after two consecutiveterms as DPL, you'd have to be one to know. At the recent MiniDebConf in Winterthur,Switzerland, Tille spoke about what he learned while serving as DPL, some ofthe initiatives he led, mistakes that he made, and his thoughts on the general resolution (GR) on largelanguage model (LLM) usage in Debian.

Sean Whitton has announcedthat the original fix for an arbitrary code execution flaw in Emacs (CVE-2024-53920) wasincomplete. Bas Alberts discovered that viewing or editing untrusted files inmodes other than Emacs's Lisp mode can also result in arbitrary codeexecution.

Just a reminder that prices for LWN subscriptions will increase afterSeptember15. Until then, the older rate still applies. See this article for details on this change.Thanks, yet again, to all of our subscribers for your support - that iswhat keeps LWN going.

The 7.3-rc3 kernel prepatch is out fortesting. Linus said: "Another fairly large rc release, and again onewith a bigger filesystem footprint that we usually see."

All of the videos from the EuroPython2026 conference, heldin Krakow, Poland from July13 through July19, are nowonline along with a recap ofthe event from conference organizers.

Kernel developers do a lot of kernel builds. Since the kernel is not asmall program, those builds can take a fair amount of time, even on a fastmachine. The kernel also has a complex build system; it is probably fairto say that few developers truly understand it, and fewer still are willingto try to improve it. Lorenzo Stoakes, armed with LLM-based assistance,decided to give it a try, though, and has managed to reduce the time ittakes to build a kernel - and not by a small amount.

PostgreSQL 19 was expected to be released in September, in keeping with the databaseproject's longstanding tradition of a major release every year. However,some late-breaking concerns about several of the features slated for inclusionhas some developers worried about the quality of the release.

One of the patches has been reverted, but several are still under heavyrevision, and an extra beta release has been slotted in to allow for additionaltesting.
