Intel is adding USB4STREAM to Linux 7.2 that lets two hosts swap raw data directly over a USB4/Thunderbolt cable via /dev/tbstreamX, bypassing the networking stack. The feature, implemented in the thunderbolt_stream driver and configurable via ConfigFS, supports multiple bidirectional streams and enables use cases like host backups, peripheral sharing, and initramfs-based recovery without network tooling.
Linux is moving to retire the outdated DTLK ISA speech-synthesizer driver (Double Talk) as part of the 7.2 kernel cycle. The driver hasn’t seen meaningful work in years, and the same hardware is supported by a separate accessibility path (Speakup), making the legacy driver largely unused. The commit argues removing it will reduce future maintenance, noting RC Systems’ DoubleTalk page remains outdated and the hardware should be retired with Linux 7.2.
Digital Foundry’s PS5 Linux tests with RPCS3 show PS3 games can run on PS5, with titles like Ridge Racer 7 and Resistance scaling to 4K/60 and 4K/30 (40–60fps range) and Heavenly Sword reaching 5K upscales, but CPU-emulation of the PS3’s SPUs cripples others (GTA4, Metal Gear Solid 4, Killzone 2/3). Turning off MLAA helps Killzone 3, yet performance remains spotty and not polished. The results underline CPU bottlenecks and suggest true PS3 emulation on PS5 may hinge on future architectures (e.g., Zen 6), even as PS5 Linux enables deeper hardware exploration.
Linux 7.1-rc5 launches with AI-assisted fixes across graphics, security, sound, and various drivers, plus improved HP/ASUS laptop x86 support and CPU power driver updates; Linus Torvalds criticizes the unusually large rc5 for late-cycle churn and hints that non-critical fixes may belong in linux-next, with a mid-June target for the stable 7.1 release.
Sony's Tim Bird unveiled the Boot-Time Wizard at the Embedded Linux Conference to help embedded Linux developers tune systems for faster boot times; currently an alpha-stage project that requires human interpretation and is available on GitHub.
Multikernel Technologies unveiled KernelScript, a beta domain-specific language aimed at simplifying Linux kernel customization and app optimizations by unifying eBPF, user-space, and kernel extension development into a type-safe language that emits C code for eBPF, user-space, and kernel modules, with a presentation at OSS 2026 and code on GitHub.
Wild Linker 0.9 is a fast Rust-based Linux linker that adds broader platform coverage, ongoing ports to Mac-OS and WebAssembly, refactors ELF handling, and introduces GNU LD/Mold Linker Plugin API support for LTO and extensibility, with no major performance changes expected.
This week highlights AI’s role in security reporting amid a flood of Linux flaws: Google’s Project Zero exposed a zero-click Pixel 10 exploit chained from a Dolby decoder memory flaw to kernel memory (patched in Feb 2026, 71 days after disclosure); Linus Torvalds praises AI tools but urges verification and fixes for AI-generated bug reports; GitHub discusses AI-generated reports in bug bounties and reports a breach via a compromised VSCode extension; Linux moves to remove zero-copy AF_ALG to curb CopyFail risks; new bugs raise root/DoS/RCE concerns (pid-fd/ssh-keysign-pwn, RDS-pintheft, nginx-rift/nginx-poolslip); Google discloses a Chromium botnet risk tied to JavaScript service workers with patch timing unclear; and a CISA credential leak in a public GitHub repo underscores ongoing access-risk from exposed tokens.
Vivaldi 8.0 debuts a major design refresh called Unified UI, collapsing browser chrome into a single continuous surface with rounded content frames and introducing six preset layouts for quick customization. The update emphasizes configurability, preserves a classic theme option, and is available now for Windows, macOS, and Linux (including ARM64 like Raspberry Pi) via Vivaldi’s site, with Snap Store and Flathub listings mentioned (one being unverified).
The Flipper One development team is seeking community help to build a distinct ARM-based Linux cyberdeck, designed to be open and well-documented with high-speed interfaces (PCIe, USB 3.0, SATA, Gigabit Ethernet) and network-focused capabilities (Wi‑Fi, 5G, Ethernet), including GUI wrappers around traditional Linux utilities; join via the Flipper One Development Portal.
Nvidia warns of a high-severity vulnerability in Windows and Linux GPU drivers and urges users to update to driver version 596.49 (older 596.36 or 482.53 for GTX 10-series are at risk); Linux users should upgrade to 590.48.01. The patch prevents attackers from gaining access to data or injecting malicious code, while Nvidia also previews a beta Auto Shader Compilation feature for RTX 50-series.
Nvidia disclosed 15 security vulnerabilities across Windows and Linux graphics drivers, with nine rated high-severity that could enable system compromise, data exfiltration, or arbitrary code execution. To mitigate, modern GeForce GPUs should update to driver 596.36 (Windows users may already have 596.49 if prompted), while GTX 10‑series and older GPUs should use 482.53; Linux users should target 590.48 and verify with nvidia-smi or nvidia-settings, updating via the OS package manager. The bulletin also covers non-gaming GPUs like Quadro, NVS, and Tesla.
Flipper unveils the Flipper One, a companion to Flipper Zero designed for networking, data transfer, and local AI. Packing an 8-core RK3576, 8GB RAM, Linux OS, Mali-G52 GPU, and an NPU, it supports 5G, Wi‑Fi 6E, two 1Gbps WAN/LAN ports, and USB-Ethernet up to 5Gbps, with additional modules for 5G. Flipper is also opening all internal development discussions via a public Developer Portal. A release date and price are not yet disclosed, and the One is positioned alongside but not as a replacement for the original Flipper Zero.
Linus Torvalds cautions that AI-assisted bug reporting in the Linux kernel is valuable only if it actually helps; the current flood of AI-generated security reports duplicates existing findings and creates pointless churn, so responsible AI use is urged and reporters are encouraged to contribute real value like patches rather than drive-by reports.
Linus Torvalds says the flood of AI-generated bug reports is making the Linux security mailing list almost unmanageable. To address this, the Linux kernel team updated triage rules ahead of the 7.1‑rc4 release: AI-detected issues should generally be reported publicly and non-sensitive, duplicates should be minimized, practitioners must provide reproducible repros and ideally a patch, and private lists are reserved for urgent, cross‑system vulnerabilities; reporters are urged to add real value beyond the AI’s initial findings.
