There is a new GnuPG update for a " critical security bug " in recent GnuPG releases. A crafted CMS (S/MIME) EnvelopedData message carrying an oversized wrapped session key can cause a stack buffer overflow in gpg-agent during the PKDECRYPT--kem=CMS handling. This can easily be used for a DoS but, worse, the memory corruption can very likley also be used to mount a remote code execution attack. The bug was introduced while changing an internal API to the FIPS required KEM API. Only versions 2.5…

GNU C Library maintainer Carlos O'Donell has announced that the project will be moving its core services away from Sourceware in favor of services hosted at the Linux Foundation. While it was clear to the GNU Toolchain leadership that requirements were coming to improve the toolchain cyber-security posture, these requirements were not clear to all project developers. As part of receiving this feedback we have worked to document and define a secure development policy for glibc and at a higher le…

The kernel's "kfunc" mechanism is a way of exporting kernel functions so that they can be called directly from BPF programs. There are over 300 kfuncs in current kernels, ranging in functionality from string processing ( bpf_strnlen() ) to custom schedulers ( scx_bpf_kick_cpu() ) and beyond. Sometimes these kfuncs need access to context information that is not directly available to BPF programs, and which thus cannot be passed in as arguments. The implicit arguments patch set from Ihor Solodrai…

The Xfce team has announced that it will be providing funding to Brian Tarricone to work on xfwl4 , a Wayland compositor for Xfce: Xfwl4 will not be based on the existing xfwm4 code. Instead, it will be written from scratch in rust, using smithay building blocks. The first attempt at creating an Xfce Wayland compositor involved modifying the existing xfwm4 code to support both X11 and Wayland in parallel. However, this approach turned out to be the wrong path forward for several reasons: Xfwm4 …

The GNU Privacy Guard (GPG) project decided to break from the OpenPGP standard for email encryption in 2023, and instead adopted its own homegrown LibrePGP specification. The GPG 2.4 branch, the last one to adhere to OpenPGP, will be reaching the end of life in mid-2026. The Fedora project is currently having a discussion about how that affects the distribution, its users, and what to offer once 2.4 is no longer receiving updates.

Curl creator Daniel Stenberg has written a blog post explaining why the project is ending its bug-bounty program, which started in April 2019: The never-ending slop submissions take a serious mental toll to manage and sometimes also a long time to debunk. Time and energy that is completely wasted while also hampering our will to live. I have also started to get the feeling that a lot of the security reporters submit reports with a bad faith attitude. These "helpers" try too hard to twist whatev…

The 6.19-rc7 kernel prepatch is out for testing. So normally this would be the last rc of the release, but as I've mentioned every rc (because I really want people to be aware and be able to plan for things) this release we'll have an rc8 due to the holiday season. And while some of the early rc's were smaller than usual and it didn't seem necessary, right now I'm quite happy I made that call. Not because there's anything particularly scary here - the release seems to be going fairly smoothly -…

Version 2.43 of the GNU C Library has been released. Changes include support for the mseal() and openat2() system calls, experimental support for building with the Clang compiler, Unicode 17.0.0 support, a number of security fixes, and much more.

Filesystems seem to be one of those many areas where the problems are well understood, but there is always somebody working toward a better solution. As a result, filesystem development in the Linux kernel continues at a fast pace even after all these years. In recent news, the EROFS filesystem is on the path to gain a useful page-cache-sharing feature, there is a new NTFS implementation on the horizon, and XFS may be about to get an infrastructure for self healing.

Version 1.5.0 of the GNU Guix package manager and the Guix System have been released. Notable improvements include the ability to run the Guix daemon without root privileges, support for 64-bit RISC-V, and experimental support for the GNU Hurd kernel. The release comes with ISO-9660 installation images, virtual machine images, and with tarballs to install the package manager on top of your GNU/Linux distro, either from source or from binaries—check out the download page. Guix users can update b…

The Linux Kernel Runtime Guard (LKRG) is a out-of-tree loadable kernel module that attempts to detect and report violations of the kernel's internal invariants, such as might be caused by an in-progress security exploit or a rootkit. LKRG has been experimental since its initial release in 2018 . In September 2025, the project announced the 1.0 version. With the promises of stability that version brings, users might want more information to decide whether to include it in their kernel.
