Version 2.8.0 of the KeePassXC password-management application has been released.

The new release brings a lot of long-awaited new features, many bugfixes, and several security updates. Among the major features are the migration from Qt5 to Qt6, Auto-Type on Wayland (Linux), configurable keyboard shortcuts, remote database synchronization with external tools, quick unlock with password on macOS, and quick unlock via Polkit on Linux. Version 2.8.0 is also the first version for which we ship native ARM64 builds for Windows and an experimental AArch64 (i.e., ARM64) AppImage for Linux.

See the changelog for a full list of new features, major changes, and bug fixes.

Nix flakes are an experimental feature of the Nix package-management tool designed to build projects in a more self-contained and reproducible way. Despite the feature's experimental status, it has become increasingly popular for open-source projects to publish flake.nix files that offer predefined development environments and build automation even when those repositories may not offer an upstream package or module for the NixOS Linux distribution. Although Nix flakes have a complicated history, and the path for stabilization is uncertain, flakes can provide useful capabilities for projects that choose to include them.

The PHP project has published PHP versions 8.5.12, 8.4.27, 8.3.36 and 8.2.35 to address two critical vulnerabilities that could allow unauthenticated remote code execution.

Who is at risk: all PHP installations serving web requests, including PHP-FPM, Apache with mod_php, php-cgi, FrankenPHP and LiteSpeed. We consider the risk highest for mod_php, with a demonstrated exploit where an unauthenticated request can trigger the attack before any application code runs.

The vulnerabilities:

• RCE via OOM corruption, CVE-2026-109618 (GHSA-w8hw-w9fx-j79w): out-of-memory handling can interrupt PHP while internal request data is only partially initialized. Request cleanup may then treat the invalid data as valid.
• RCE via stale global state, CVE-2026-109619 (GHSA-6wmf-4rv5-p3rp): request-owned internal state can survive after its backing memory has been freed. A later request handled by the same worker may use that stale state before normal initialization resets it.

PHP versions older than 8.1 will not receive updates from the project, though the project has provided some patches for PHP 7.4, PHP 8.0, and PHP 8.1 to assist in creating backports. According to the announcement, Linux distributions and vendors received patches in advance, so updated packages should be coming soon.

Greg Kroah-Hartman has announced the release of the 7.2.12, 6.18.58, 6.12.114, and 6.6.160 stable kernels. Each contains a number of important fixes; users are advised to upgrade.

Setuid (and setgid) binaries have long been a source of headaches, and security vulnerabilities, on Linux systems. They are largely seen as something to be avoided; SUSE's security team, for example, forbids the inclusion of setuid or setgid binaries in packages unless they have been reviewed and explicitly allowed. Thorsten Kukuk wants to go a step further and disallow them entirely. At the 2026 All Systems Go! conference, he spoke about his work to disable setuid system-wide, as well as some of the hurdles that remain.

Mozilla has announced that it has received a report that private keys associated with eight eMudhra intermediate certificates have been compromised:

These keys could allow attackers to issue fraudulent HTTPS certificates for websites they do not control. An attacker who could intercept a user's connection could use those certificates to impersonate websites and potentially read or modify traffic.

Mozilla has blocked the affected certificates using its OneCRL centralized list of revoked certificates, and has updated the trusted certificate list in Network Security Services (NSS) 3.131.1.

There is a single-page site about the compromise that goes into more detail. According to the site the certificates have also been blocked in Chrome since October 17, Apple devices since the 19th, and Microsoft blocked the certificates on the 20th. There is also a table that displays whether a browser or other client still trusts the compromised certificates.

The NetBSD foundation has issued instructions to block the certificates on NetBSD installations. Users of other browsers and operating systems may wish to check for updates or guidance to disable the compromised certificates.

OpenBSD 8.0 has been released. There are many new features, including the addition of hibernate support for arm64, an increase in the kernel virtual address space for amd64 to 512GB, quite a few improvements for the qwx driver that supports Qualcomm WiFi 6 devices, and much more. See the full changelog for details.

Mike Rapoport has announced the release of the video recordings from the 2026 Linux Plumbers Conference (LPC), which was held in Prague from October 5 through October 7. Find the complete set via the YouTube playlist or look for the video links in the schedule. See also LWN's coverage of talks from LPC.

The GNOME Project has provided GNOME OS for some time; until now, the project only provided a "Nightly" edition that was built from the latest commits and was aimed solely at GNOME developers. Adrian Vovk has now announced the release of GNOME OS Preview, which is intended for a non-developer audience:

GNOME OS Preview is the current GNOME OS Nightly, but without the "nightly" aspect. Instead, it's built from the latest stable GNOME release (GNOME 51.1, at the time of writing). GNOME OS Preview lives in the same branches on GitLab as the stable org.gnome.Platform Flatpak runtimes.

GNOME OS Preview is only a few weeks old, so it has only seen limited real-life testing so far. We therefore expect people will uncover some issues initially. That said, Preview is significantly more stable than Nightly, which dozens of people have been daily driving without major issues for over a year. Thus, we're feeling confident that Preview is going to be reliable enough for daily use by non-developer enthusiasts.

While Preview is meant for non-developers, it is not considered complete or stable for the broader public. There are a number of features, listed in Vovk's post, that need to be implemented before the project is ready to declare GNOME OS "ready for prime time". Adventurous users, who might not mind having to reinstall the OS once a stable version is declared, can download and start using GNOME OS Preview today.

As part of KDE's 30th anniversary celebration, the project has released The KDE Documentary — A Story of Free Software Underdogs (YouTube video):

The story starts in 1996, when Matthias Ettrich, a student at the University of Tübingen, posted to a Usenet group asking for programmers to help build a desktop for Linux. What followed became KDE, one of the largest free software communities in the world. KDE made Linux usable as a desktop for people who weren't system administrators, giving it a complete, consistent graphical environment at a time when there was none.

The film covers the highs and lows of three decades of KDE: the Qt licensing fight and the rivalry with GNOME; the success of KHTML, the browser engine that became the basis of Apple's WebKit and Google's Chrome; and the contentious release of KDE 4 and the rebuild that followed.

Canonical has announced the release of Ubuntu 26.10 ("Stonking Stingray"):

Ubuntu 26.10 advances enterprise security features, completes the rollout of the Rust-based uutils coreutils, and strengthens integrations for user authentication using Microsoft Entra ID.

[...] Ubuntu 26.10 also ships with GNOME 51, bringing a smoother, more responsive desktop, better display handling, improved accessibility, and refinements across core applications. In addition, the Ubuntu App Center now provides a more consistent experience for managing snaps and debs.

See the release notes for a list of new features as well as incompatible changes between 26.10 and prior Ubuntu releases.

Greg Kroah-Hartman has announced the release of the 7.2.11, 6.18.57, 6.12.113, 6.6.159, 6.1.190, 5.15.223, and 5.10.272 stable kernels. This series includes, among other things, a fix for a critical vulnerability (CVE-2026-99999). The flaw in skb_checksum_help() would allow an IPv4 packet with bad checksum metadata to "corrupt the network header and cause a bunch of mischief" in the words of patch author Michael S. Tsirkin. As usual, all users are advised to upgrade.
