Driver fixes dominate at ~60%, with networking at ~20%. The sound subsystem pull was notably oversized, including device-specific quirks for hardware like Corsair Virtuoso and Lenovo Legion 7, plus security fixes for use-after-free vulnerabilities, stack leaks, race conditions, and out-of-bounds accesses — several of which were reportedly found by AI/LLM coding agents. A notable bug fixed: AMD Zen 5 CPUs were being misidentified as Zen 6 due to incorrect ID range assignments. Also included is a fix for x86 memcmp() instruction reordering that caused unbootable VMs under Xen, a workaround for buggy Western Digital SATA drives, and DRM graphics fixes. The stable 7.2 release is expected in roughly two weeks. ## Content Linux 7.2-rc6 is out, and both Linus Torvalds and sound subsystem maintainer Takashi Iwai are a bit uncomfortable with how big it got. Torvalds called it potentially the biggest rc6 by commit count in years — 537 non-merge commits since rc5. The breakdown is roughly what you'd expect late in a cycle: driver fixes account for about 60%, networking around 20%, with the rest spread across arch, tooling, and filesystems. He attributed some of the backlog to conference timing, which tends to compress patch submissions. ## Sound fixes that got out of hand Iwai described the sound pull as "far larger than wished." It includes device-specific quirks for a fairly long list of hardware: Corsair Virtuoso, Razer Barracuda X 2.4, HP Victus 16, Lenovo Legion 7, and others — covering microphone problems, mute LED fixes, and audio not working at all on certain platforms. Beyond the quirks, the pull also addresses several security issues: use-after-free vulnerabilities, stack leaks, potential race conditions, and out-of-bounds accesses. Iwai noted that a number of these were found by AI/LLM coding agents, which Torvalds also flagged as a noticeable trend in this cycle. Whether that's a good thing probably depends on how you feel about the overall patch volume. Iwai said he plans to throttle sound patch activity as the cycle winds down. ## AMD Zen 5 CPUs misidentified as Zen 6 One of the more concrete bugs fixed in rc6: some AMD Zen 5 CPUs were being misidentified as Zen 6 due to an incorrect ID range assignment. The fix reserves 0xd0–0xd7 for Zen 5 and updates the Zen 6 ranges to 0xc0–0xcf, 0xd8–0xef, 0x50–0x5f, and 0x80–0xaf. The same x86 fixes pull includes a correction to x86 `memcmp()` to prevent instruction reordering that was causing unbootable VMs under Xen. ## Other notable fixes - A workaround for buggy Western Digital SATA drives - DRM graphics driver fixes ## What's next The stable Linux 7.2 release is expected in roughly two weeks. Torvalds expressed hope that things calm down before then — a sentiment Iwai clearly shares. ## Similar posts on daily.dev - [Linux 7.0-rc3 Released: "Some Of The Biggest In Recent History"](https://daily.dev/posts/linux-7-0-rc3-released-some-of-the-biggest-in-recent-history--hyn7dy7pw) · Phoronix · 0 upvotes · 0 comments - [Linux 7.0-rc2 Released: "So I'm Not Super-Happy With How Big This Is"](https://daily.dev/posts/linux-7-0-rc2-released-so-i-m-not-super-happy-with-how-big-this-is--lnpxqpqrt) · Phoronix · 1 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#linux](https://daily.dev/tags/linux), [#hardware](https://daily.dev/tags/hardware), [#amd](https://daily.dev/tags/amd) [View this post on daily.dev](https://daily.dev/posts/linux-7-2-rc6-is-unusually-large-with-driver-quirks-security-fixes-and-an-amd-cpu-misidentificati-2vtr8a0uh) ```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 7.2-rc6 is unusually large, with driver quirks, security fixes, and an AMD CPU misidentification bug","url":"https://daily.dev/posts/linux-7-2-rc6-is-unusually-large-with-driver-quirks-security-fixes-and-an-amd-cpu-misidentificati-2vtr8a0uh","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/linux-7-2-rc6-is-unusually-large-with-driver-quirks-security-fixes-and-an-amd-cpu-misidentificati-2vtr8a0uh"},"datePublished":"2026-08-03T00:12:50.320Z","dateModified":"2026-08-03T00:13:34.022Z","description":"Linux 7.2-rc6 has landed with an unusually high commit count — 537 non-merge commits since rc5, making it potentially the largest rc6 by commit count in years....","isAccessibleForFree":true,"articleSection":"Collections","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collections","logo":"https://media.daily.dev/image/upload/s--fk_6ycEi--/f_auto,q_auto/v1780996001/logos/collections?_a=BAMAMiWQ0","url":"https://daily.dev/sources/collections"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/linux-7-2-rc6-is-unusually-large-with-driver-quirks-security-fixes-and-an-amd-cpu-misidentificati-2vtr8a0uh","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,linux,hardware,amd","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collections","item":"https://daily.dev/sources/collections"},{"@type":"ListItem","position":3,"name":"Linux 7.2-rc6 is unusually large, with driver quirks, security fixes, and an AMD CPU misidentification bug"}]} ```
