October was a busy month for Linux and open-source software, with coverage spanning kernel development, desktop distributions, hardware support and performance testing. Phoronix reported 308 original news articles and 16 Linux hardware reviews or multi-page benchmark features during the month.
Artificial intelligence was one of the main themes. Linux creator Linus Torvalds used Claude Code while working on a substantial kernel improvement related to page-cache reads, and later described how AI-assisted work helped make patches easier to understand while also exposing additional long-standing bugs. A later reworking of the code by Meta engineer Kiryl Shutsemau produced promising performance results.
The growing role of AI in kernel development also prompted discussion about project policy. Kernel developers considered removing the requirement for an “Assisted-by:” tag on patches created with AI tools, amid the increasingly common use of large language models. Separate reports examined the potential for AI to help reverse-engineer hardware and support open-source implementations of applications associated with Adobe Photoshop, Premiere and Lightroom.
Microsoft’s release of Defender for the Linux desktop was another major development. The company said the software was intended to secure Linux desktops as more developers use the platform, extending Microsoft’s existing Linux security efforts beyond server environments.
Kernel security also drew attention after several vulnerability reports were accidentally posted to the public Linux kernel mailing list instead of the private security list. The reports had not yet been fixed in the mainline kernel at the time of publication, although some patches were being tested or queued in development branches. Reported CVSS scores reached 9.0.
Other kernel work included significant improvements for older AMD graphics processors. Timur Kristóf of Valve’s Linux graphics team presented work enhancing the AMDGPU driver for graphics cards from the GCN 1.0 and 1.1 era. Developers also prepared initial device-tree support for Apple systems using the base M4 chip and for the MacBook Neo with an A18 Pro processor.
Several performance-focused kernel changes were highlighted as well. A FAT32 change merged for Linux 7.4 showed substantial speed improvements, while updates to the early boot-time physical-memory allocator reduced the reported runtime of a test from roughly 268 seconds to about 50 milliseconds. Torvalds also merged the removal of the historical __get_user() and __put_user() functions, described as unsafe.
The month’s broader software coverage included Linux 7.3, Ubuntu 26.10 and KDE Plasma 6.8. Valve released a Steam beta that made the Linux client a 64-bit application, while a new Wayland protocol was proposed to help remote software such as VNC servers operate in a Wayland environment. Fedora 45 was delayed after missing its release target and then receiving another no-go decision because of unresolved blocker bugs.
Open-source projects also faced setbacks. Siemens ended the OpenRadioss project and closed access to its open-source version, which Altair Engineering had released under the GNU AGPL in 2022. Siemens acquired Altair the previous year.
On the hardware side, Phoronix tested CachyOS, Fedora 45 and Ubuntu 26.10 on an AMD Ryzen 9 9900X3D2 system, and published initial Linux benchmarks for Qualcomm’s Snapdragon X2 Elite Extreme in an ASUS Zenbook laptop. Other reviews covered the Star Labs StarFighter Ultra Linux laptop, the Framework Laptop 12 with Intel Core 3 “Wildcat Lake,” and memory-speed differences involving LPDDR5-5467, LPDDR5-6400 and LPDDR5-7467.
The month also included comparisons of AMD ROCm and Vulkan performance for local Llama.cpp workloads, testing of Mesa’s Rusticl OpenCL driver against AMD’s ROCm implementation on Strix Halo, and NVIDIA Vera processor benchmarks against AMD EPYC and Intel Xeon systems. Additional testing examined NVIDIA Vera performance in single- and dual-socket configurations.
