Version:next-20260806 (linux-next) Released:2026-08-06

The kernel is able to run a few types of executable files, including native binaries in the ELF format and interpreted programs that begin with the #! marker. It also, however, has a mechanism, called binfmt_misc, that can be configured from user space to enable the transparent execution of programs in just about any format. This feature has been relatively static for years, but it seems likely to receive some significant updates in the near future, including the ability to load BPF programs that can decide how to run a given program.

Version 0.10 of the uutils project's Rust Coreutils has been released. This release focused on compatibility with the GNU Core Utilities suite, with Rust Coreutils now passing 645 of 690 tests, up from 625 with version 0.9.0. Notable changes in this release include addition of the mv --exchange option, an OpenSSL backend for checksum utilities, applying SELinux labels at creation when using mkdir, mkfifo, and mknod, as well as a number of performance and security improvements.

The project has an online playground that runs the Rust Coreutils directly in the browser via WebAssembly for those who would like to try the utilities without installing them. LWN covered the uutils project in February 2025.

Security updates have been issued by Debian (7zip, kernel, libde265, and p7zip), Mageia (tomcat), Oracle (fence-agents, frr10, kernel, ldns, libgcrypt, mingw-glib2, nodejs24, osbuild-composer, p11-kit, php8.4, sg3_utils, and thunderbird), Red Hat (libXfont2), and SUSE (containerd, evince, libXfont2, nginx, openssl-3, pcp, php7, php8, python-Django, python-httplib2, python-nltk, rrdtool, vifm, and wireshark).

SmartOS is an open-source UNIX-like operating system based on illumos, a community fork of OpenSolaris. It features four technologies - ZFS (a combined file system and logical volume manager), DTrace (a dynamic tracing framework for troubleshooting kernel and application problems), Zones (a lightweight virtualisation solution), KVM and bhyve (two full virtualisation solutions for running a variety of guest operating systems, including Linux, Windows, BSD and Plan9). SmartOS is designed to be particularly suitable for building clouds and generating appliances.

CalamaroOS is a Gentoo-based Linux distribution for the desktop, using either KDE Plasma or Xfce desktop environment. It features the Calamares system installer, out-of-the-box support for Flatpak packages, support for BTRFS, XFS and F2FS filesystems, and the systemd software suite for system and service management. The project's goal is to bring the power of Gentoo Linux to an average user by eliminating the complex and time-consuming process associated with the classic Gentoo install method.
