To fit on real hardware, these models run in INT8, a compressed 8-bit number format, and that compression opens a door: Rowhammer, a well-known hardware exploit that flips bits in memory chips without touching a line of software. Testing four models across three different ways of generating motor commands, the team found that a few carefully chosen flips, sometimes just one to five, cut task success to zero, while hundreds of random flips changed nothing. Newer flow-matching models were tougher, needing 100 to 300 targeted flips, though the researchers built a technique that shrank one leading model's break point from roughly 1000 flips down to about 100. On an actual robot, the attack took a 70 percent clean success rate to 0 out of 20 runs.\n\nRowhammer has been used to break into cloud servers and phones since 2014; this is among the first papers to point it at embodied AI, where a corrupted model does not just output bad text but sends a physical robot the wrong instructions on a factory floor or in a warehouse. The upside: protecting as little as 5 percent of a model's weights from tampering pushed the break threshold from 3 flips back up to 100, so the fix looks cheaper than the exploit.\n\nIt is a reminder that squeezing AI models down to run fast on cheap chips has a cost nobody put on the spec sheet: a shrinking margin between fine and completely broken.","[\"robotics\",\"rowhammer\",\"ai security\",\"quantization\"]","2026-08-18T04:00:00.000Z","2026-08-18T17:42:35.693Z","2026-08-18T17:42:47.568Z","published",null,[],"security",[26,27,28,29],"robotics","rowhammer","ai security","quantization",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.15475",0,{"sections":36},[37,42,45,50,55,60,65,70,75,79,84,89,94,99],{"name":38,"slug":39,"count":40,"latest_published_at":41},"AI","ai",3293,"2026-08-20T04:00:00.000Z",{"name":43,"slug":24,"count":44,"latest_published_at":41},"Security",435,{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",69,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
