Linux News: AI Slop, Linus Torvalds Vibe Coding, Rust, Wayland & NEW Hardware

Summary

This Linux and open-source news roundup covers AI-assisted development, security, kernel performance, Rust adoption, and desktop updates.

AI in open-source development

A Linux Foundation survey of more than 300 developers found that respondents believe generative AI can reduce coding time by as much as 50%. The presenter cautions that this is self-reported experience, not a direct measurement of software quality.

AI-generated contributions are also increasing review workloads. Fifty-two percent of developers reported spending more time on reviews, rising to 64% at large projects. The survey found that 25% of incoming pull requests were considered “AI junk,” while only 35% of projects had a formal AI policy. The presenter warns of reviewer burnout and the risk of accepting code that contributors do not fully understand.

Security and code maintenance

Trend Micro’s Zero Day Initiative accidentally disclosed seven Linux kernel vulnerabilities to the public kernel mailing list. One reported KSMBD issue was described as a possible remote-code-execution vulnerability with a severity score of 9.0; fixes were said to be in progress.

The presenter also notes that AI-generated patches targeting obsolete hardware have become a maintenance burden. The kernel’s EDAC subsystem plans to remove four outdated hardware drivers that are difficult to test and maintain.

A separate report covers two critical PHP vulnerabilities involving memory errors and potential remote code execution. Emergency updates were issued for affected PHP branches, and real-world attacks had reportedly been observed.

AI-assisted kernel work and performance

Linus Torvalds used an AI coding assistant to explore a kernel optimization for workloads in which many CPU threads read small amounts of data from the same file. A kernel developer reviewed and reworked the initial code into patches. The change uses read-copy-update techniques to reduce shared-page reference-counting overhead. Benchmarks were discussed for ext4, XFS, tmpfs, and other devices.

Torvalds also used AI assistance while cleaning up deprecated kernel interfaces, including the old get_user and put_user functions. Other developers are expected to complete and test the work.

A Linux 7.4 optimization replaces a linear search with a binary search during early memory-region lookup. In the tested case, the reported search time fell from 268 seconds to roughly 50 milliseconds.

Planned Btrfs improvements target Zstandard decompression, inode extent-map locking, and reflink operations. The presenter cites decompression gains of up to 8 MB/s and 10–20% less processing time in some locking cases.

Graphics, hardware, and Rust

Aurora Silicon created Borealis, an AI-permissive fork of Asahi Linux’s Apple Silicon Vulkan driver, based on the Honeycrisp driver. It is being developed outside Mesa. The presenter notes the potential for duplicated effort and fragmentation, and says no performance benefit has yet been demonstrated.

Mesa clarified that AI-assisted contributions are permitted, provided contributors review and edit their submissions. Its policy focuses on submitted code rather than regulating developers’ private workflows.

Linux 7.3 was described as bringing I/O and hardware improvements, preparation for future AMD Zen processors, Steam controller support, improvements for older AMD GPUs, and bug and security fixes.

A new 46-core RISC-V server processor from SpaceMIT was presented with eight DDR5 memory channels and PCIe 5.0. It can support systems with up to 92 cores, though its real-world competitiveness remains an open question.

Linux 7.4 is set to receive around 17,000 lines of Rust-related code, primarily infrastructure, including a zero-copy library. Systemd 263 also adds support for writing selected components in Rust, with a keyring-related component under development.

Distribution and desktop news

Fedora 45 was delayed for a second time because of unresolved issues involving encrypted storage, updates, and installation. The next target date mentioned is November 3. The presenter says Fedora 44 users do not need to rush to upgrade.

COSMIC 1.1 improves hybrid-GPU selection and Wayland dialog handling, alongside updates to libraries, applets, and the launcher.

KDE Plasma 6.9 makes KWin Wayland picture-in-picture stable and enabled by default. The update also improves Brave browser integration and multi-monitor behavior, along with various fixes.

The closing desktop and distribution segment describes an AI-oriented project and mentions browser-launch, scheduler, and graphics-related improvements. The captions inconsistently identify it as AlmaLinux, while the video context identifies it as Omarchy, so the exact project details are uncertain.

Reviews, guides, and promotions

No review, tutorial, or step-by-step guide is presented. The video includes a brief promotional segment for Star Labs Linux laptops, highlighting Linux preinstallation and Coreboot firmware. It is an advertisement rather than an independent review.
