Denis Efremov of Oracle fixed a possible stack out-of-bounds issue in the floppy driver as reported by the Kernel Address Sanitizer, plus a regression dating back to a 2017 code refactor. Cen Zhang found some data races in the floppy driver using unspecified tooling. Finn Thain's fixes to the SWIM driver for old Apple Macintosh floppy controllers were tested on a Mac Quadra 650, LC III, Quadra 700, and IIvx. The same pull request adds Apple M4 T8132 ANS2 NVMe support. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new hardware support landed in the Linux 7.4 block subsystem pull request? The Linux 7.4 block pull request adds Apple M4 T8132 ANS2 NVMe support, enabling NVMe storage on Apple M4-based hardware. The same pull request also includes numerous floppy disk driver fixes, including a stack out-of-bounds fix by Denis Efremov of Oracle and 33 SWIM driver fixes by Finn Thain for old Apple Macintosh floppy controllers. _Track kernel storage support changes like Apple M4 NVMe enablement on daily.dev as they merge._ ### Were any bugs found in the Linux floppy disk driver recently? Yes, Denis Efremov of Oracle fixed a possible stack out-of-bounds issue in the floppy driver reported by the Kernel Address Sanitizer, and also fixed a regression stemming from a 2017 code refactoring. Separately, Cen Zhang found data races in the floppy driver using unspecified tooling, merged as part of the Linux 7.4 block pull request. _Developers debugging legacy kernel drivers can follow fixes like these via daily.dev._ ## Similar posts on daily.dev - [Linux Patches Enable Apple M4 NVMe Support](https://daily.dev/posts/linux-patches-enable-apple-m4-nvme-support-jeeewbcdm) · Phoronix · 0 upvotes · 0 comments - [Linux 7.1 brings new NTFS driver, Steam Deck OLED audio fix \+ more](https://daily.dev/posts/linux-7-1-brings-new-ntfs-driver-steam-deck-oled-audio-fix-more-jfil3igpw) · omg\! ubuntu\! · 17 upvotes · 1 comments - [Apple NVMe Linux Driver Sees Fixes After Being Bitten By New Firmware](https://daily.dev/posts/apple-nvme-linux-driver-sees-fixes-after-being-bitten-by-new-firmware-ya2grvmvj) · Phoronix · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#linux](https://daily.dev/tags/linux), [#hardware](https://daily.dev/tags/hardware) [View this post on daily.dev](https://daily.dev/posts/linux-7-4-block-updates-range-from-floppy-disk-driver-fixes-to-apple-m4-nvme-support-m2yvgadhb) ```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 7.4 Block Updates Range From Floppy Disk Driver Fixes To Apple M4 NVMe Support","url":"https://daily.dev/posts/linux-7-4-block-updates-range-from-floppy-disk-driver-fixes-to-apple-m4-nvme-support-m2yvgadhb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/linux-7-4-block-updates-range-from-floppy-disk-driver-fixes-to-apple-m4-nvme-support-m2yvgadhb"},"datePublished":"2026-10-25T00:55:01.599Z","dateModified":"2026-10-25T00:55:39.801Z","description":"The Linux 7.4 block subsystem pull request merges fixes spanning floppy disk drivers to Apple M4 NVMe support.
