Building on a decade of Rowhammer research that previously targeted CPU DRAM, these attacks extend the technique to high-performance GPU memory, going far beyond earlier GPU Rowhammer work that only achieved eight bitflips with limited impact. The attacks are particularly concerning given that expensive GPUs are routinely shared among many users in cloud settings. ## Full article daily.dev links to this article rather than hosting it.

What's the point of sharing a GPU anyways, it's not like I've ever seen one with enough VRAM. ## Similar posts on daily.dev - [Schneier on Security](https://daily.dev/posts/schneier-on-security-koiwbolx4) · Schneier on Security · 0 upvotes · 0 comments - [New GPUBreach attack enables system takeover via GPU rowhammer](https://daily.dev/posts/new-gpubreach-attack-enables-system-takeover-via-gpu-rowhammer-op8ygz9ex) · BleepingComputer · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#nvidia](https://daily.dev/tags/nvidia) [View this post on daily.dev](https://daily.dev/posts/new-rowhammer-attacks-give-complete-control-of-machines-running-nvidia-gpus-870gt3du3) ```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":"New Rowhammer attacks give complete control of machines running Nvidia GPUs","url":"https://daily.dev/posts/new-rowhammer-attacks-give-complete-control-of-machines-running-nvidia-gpus-870gt3du3","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/new-rowhammer-attacks-give-complete-control-of-machines-running-nvidia-gpus-870gt3du3"},"datePublished":"2026-04-03T13:56:25.610Z","dateModified":"2026-04-03T13:56:53.598Z","description":"Two new Rowhammer-based attacks, GDDRHammer and GeForgeHammer, demonstrate how malicious users sharing Nvidia GPUs in cloud environments can gain full root...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/0aeb740cdc3d3eee4de00138add440d7?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/0aeb740cdc3d3eee4de00138add440d7?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Hacker News","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":"Hacker News","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/hn","url":"https://daily.dev/sources/hn"},"commentCount":1,"discussionUrl":"https://daily.dev/posts/new-rowhammer-attacks-give-complete-control-of-machines-running-nvidia-gpus-870gt3du3","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":1}],"keywords":"security,nvidia","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Hacker News","item":"https://daily.dev/sources/hn"},{"@type":"ListItem","position":3,"name":"New Rowhammer attacks give complete control of machines running Nvidia GPUs"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/new-rowhammer-attacks-give-complete-control-of-machines-running-nvidia-gpus-870gt3du3","comment":[{"@type":"Comment","text":"Big whoop, now Nvidia can slow down all our GPUs so they can sell us new ones.
