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...

Security Week is one of several outlets reporting that the funding for the CVE program at MITRE disappears as of April 16. Maintained by MITRE Corporation, a not-for-profit organization that operates federal R&D centers, the CVE program is funded through multiple channels,...
Version 25.0 ('Zetar') of the Arch-based Manjaro Linux distribution is now available. This release includes Linux kernel 6.12, GNOME 48, KDE 6.3, Xfce 4.18, and more.
The Fedora Project has announced the release of Fedora Linux 42, with 'what's new' articles for Fedora Workstation and Fedora KDE Plasma Desktop. There is also a last-minute warning about the live media for the release: We discovered a problem with the Live boot media at...
Fedora Linux 42 has been released with many incremental improvements and updates. In this development cycle, the KDE Plasma Desktop has finally gotten a promotion from a spin to an edition, the new web-based user interface for the Anaconda installer makes its debut, and the...
It is common, on NUMA systems, to try to allocate all memory on the local node, since it will be the fastest. That is not the only possible policy, though; another is weighted interleaving, which seeks to distribute allocations across memory controllers to maximize the...
Security updates have been issued by AlmaLinux (glibc), Red Hat (kernel and kernel-rt), Slackware (perl), SUSE (haproxy, kernel, and webkit2gtk3), and Ubuntu (cimg, perl, protobuf, and webkit2gtk).

Version 3.0 of the Pinta image editor has been released. The most notable change in this release is that Pinta has been ported to GTK 4.0 and libadwaita. It also includes a number of improvements, new effects, and bug fixes.
BPF is, famously, not part of the kernel's promises of user-space stability. New kernels can and do break existing BPF programs; the BPF developers try to fix unintentional regressions as they happen, but the whole thing can be something of a bumpy ride for users trying to...
Andrew Morton, the lead maintainer for the kernel's memory-management subsystem, tends to be quiet during the Linux Storage, Filesystem, Memory-Management, and BPF Summit, preferring to let the developers work things out on their own. That changes, though, when he leads the...
Security updates have been issued by Debian (glib2.0, jinja2, kernel, mediawiki, perl, subversion, twitter-bootstrap3, twitter-bootstrap4, and wpa), Fedora (c-ares, chromium, condor, corosync, cri-tools1.29, exim, firefox, matrix-synapse, nextcloud, openvpn,...
Linus has released 6.15-rc2 for testing. 'Nothing particularly stands out to me, but it's early in the release yet, so let's see how it goes.'

Knowing how frequently accessed a page of memory is (its 'hotness') is a key input to many memory-management heuristics. Jonathan Cameron, in a memory-management track at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, pointed out that the number of...

Eduard Zingerman presented a daring proposal that 'makes sense if you think about it a bit' at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit. He wants to inline performance-sensitive kernel functions into the BPF programs that call them. His prototype ...
Security updates have been issued by AlmaLinux (delve and golang and go-toolset:rhel8), Debian (webkit2gtk), Fedora (openvpn, thunderbird, uboot-tools, and zabbix), SUSE (expat, fontforge, govulncheck-vulndb, and kernel), and Ubuntu (haproxy and libsoup2.4, libsoup3).

Building on the discussion in the two previous sessions on untorn (or atomic) writes, for buffered I/O and for XFS using direct I/O, Ojaswin Mujoo remotely led a session on support for the feature on ext4. That took place in the combined storage and filesystem track at the...
Over on the Red Hat Developer site, David Malcolm has an article about improvements in GCC 15, specifically focusing on the diagnostic information that the compiler emits. This includes ASCII art with a '⚠️' warning emoji to display the execution path when it detects a...
