The 6.15-rc3 kernel prepatch is out for testing. 'There's absolutely nothing of huge note here as far as I can tell. Just a fair number of small fixes all over the place'.

The New Stack looks at EU OS, an attempt to create a desktop system for the European public sector. EU OS is not a brand-new Linux distribution in the traditional sense. Instead, it is a proof-of-concept built atop Fedora's immutable KDE Plasma spin (Kinoite). EU OS takes...
The final session in the memory-management track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit was a brief, last-minute addition run by Kalesh Singh. The kernel's readahead mechanism is generally good for performance; it ensures that data is...
Adding tracepoints to some kernel subsystems has been controversial—or disallowed—due to concerns about the user-space ABI that they might create. The virtual filesystem (VFS) layer has long been one of the subsystems that has not allowed any tracepoints, but that may be ...

Version 14.5 of the Tor Browser has been released. Notable features in this release include the addition of Connection Assist for the Android version of the Tor Browser, and language support for Belarusian, Bulgarian, and Portuguese for all versions of the browser. Should...
The kernel's memory controller works within the control-group mechanism to enforce memory-usage limits on groups of processes. This component has often had performance problems, so there is continual interest in optimizing it. Shakeel Butt led a session during the...
Security updates have been issued by Debian (chromium and libapache2-mod-auth-openidc), Oracle (expat, freetype, glibc, grub2, gvisor-tap-vsock, and kernel), Red Hat (grub2 and webkit2gtk3), and SUSE (apache2-mod_auth_openidc, cosign, gitoxide, govulncheck-vulndb,...

Debian's Advanced Package Tool (APT) is the suite of utilities that handle package management on Debian and Debian-derived operating systems. APT recently received a major upgrade to 3.0 just in time for inclusion in Debian 13 ('trixie'), which is planned for release...
GNOME contributor Michael Catanzaro has written a blog post about a noteworthy vulnerability in GNOME's help browser, Yelp. I don't normally blog about particular CVEs, but Yelp CVE-2025-3155 is noteworthy because it is quite severe, public for several weeks now, and not...
Allowing directories to be modified in parallel was the topic of Jeff Layton's filesystem-track session at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF). There are certain use cases, including for the NFS and Lustre filesystems, as...
The BPF verifier is not magic; it cannot solve the halting problem. Therefore, it has to err on the side of assuming that a program will run too long if it cannot prove that the program will not. The ultimate check on the size of a BPF program is the one-million-instruction ...
Sergiu Gatlan reports that the US government has extended funding for the Common Vulnerabilities and Exposures (CVE) program, following yesterday's reports that funding would run out as of April 16. 'The CVE Program is invaluable to cyber community and a priority of CISA,'...
As a system runs, its memory becomes fragmented; it does not take long before the allocation of large, physically contiguous memory ranges becomes difficult or impossible. The contiguous memory allocator (CMA) is a kernel subsystem that attempts to address this problem, but...
Security updates have been issued by AlmaLinux (gvisor-tap-vsock, kernel, and kernel-rt), Fedora (chromium, dnf, dotnet9.0, golang, lemonldap-ng, mariadb10.11, perl-Crypt-URandom-Token, perl-DBIx-Class-EncodedColumn, php-tcpdf, podman-tui, and trunk), Red Hat...
In the first filesystem-track session at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), virtual filesystem (VFS) layer co-maintainer Christian Brauner had a few different topics he wanted to talk about. Issues on the agenda included...
