Key highlights include kernel tracing enhancements (function-graph tracer return values, timer-latency tracer user-space management, fprobe events), filesystem additions (mountpoint-at-mountpoint for containers, new cachestat() syscall, Overlay filesystem data-only layers), and secretmem enabled by default. Collabora contributed significantly, including hardware enablement for MediaTek SoCs (MT8192, MT8195, MT8186, MT8188, MT6795), extensive Rockchip RK3588 support (PMIC, ADC, AV1 stateless decoder, timer, OTP), and an urgent Zenbleed (CVE-2023-20593) mitigation patch extending coverage to the Steam Deck's AMD custom APU. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does the Zenbleed CVE-2023-20593 vulnerability affect the Steam Deck and is there a kernel fix? Yes, the Steam Deck's AMD custom APU is affected by Zenbleed (CVE-2023-20593), which targets AMD Zen 2 architecture processors. The initial mitigation did not cover this APU, so an urgent patch was submitted for Linux kernel 6.5 and backported to stable releases as a fallback fix until a proper CPU microcode update becomes available. _Developers tracking AMD security patches and kernel mitigations for embedded or gaming hardware follow coverage like this on daily.dev._ ### What new filesystem features were added in Linux kernel 6.5? Linux kernel 6.5 adds the ability to mount a filesystem at another mounted filesystem's mountpoint, which is primarily useful for containers. It also introduces the cachestat() system call, letting user space query which open file pages are resident in RAM, and adds data-only layer support to the Overlay filesystem. _Engineers building container runtimes or storage layers keep up with kernel filesystem changes on daily.dev._ ## Similar posts on daily.dev - [Kernel 7.2: RK3588 media, smarter GPU memory, and Rust foundations](https://daily.dev/posts/kernel-7-2-rk3588-media-smarter-gpu-memory-and-rust-foundations-vrpih8voj) · Collabora Blog · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#amd](https://daily.dev/tags/amd) [View this post on daily.dev](https://daily.dev/posts/linux-kernel-6-5-usb4v2-and-wifi7-have-arrived-wpgzbk5in) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Linux kernel 6.5: USB4v2 and Wifi7 have arrived","url":"https://daily.dev/posts/linux-kernel-6-5-usb4v2-and-wifi7-have-arrived-wpgzbk5in","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/linux-kernel-6-5-usb4v2-and-wifi7-have-arrived-wpgzbk5in"},"datePublished":"2026-08-11T08:53:56.014Z","dateModified":"2026-08-11T09:15:41.957Z","description":"Linux kernel 6.5 has been released, bringing USB4v2 and WiFi7 support alongside numerous improvements.
