Researchers identified those bottlenecks and built kAgent: a workflow-based agent that inspects execution logs, forms natural-language hypotheses about root causes, generates candidate patches, and validates them by reproducing the original crash. A co-designed toolstack called kGym++ handles the agent's specialized requests. On the kBenchSyz benchmark, kAgent resolved 54.5% of crashes without any file-location hints, and 65% when given the correct file.\n\nKernel fuzz bugs often sit in a queue for months because the developer pool with the expertise to fix them is small, and many are security-sensitive. A tool that can autonomously close more than half of those crashes shifts the economics of kernel maintenance and shortens the window between discovery and patch.\n\nThe 65% figure is the more flattering number — and it still depends on a human knowing which file to point at.","[\"linux\",\"kernel\",\"ai\",\"security\"]","2026-07-07T04:00:00.000Z","2026-07-07T17:26:52.699Z","2026-07-07T17:26:55.516Z","published",null,[],"ai",[26,27,24,28],"linux","kernel","security",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2504.20412",0,{"sections":35},[36,40,44,49,54,59,64,69,74,78,83,87,92,97],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":28,"count":42,"latest_published_at":43},"Security",294,"2026-07-15T19:59:48.000Z",{"name":45,"slug":46,"count":47,"latest_published_at":48},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":79,"slug":80,"count":81,"latest_published_at":82},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":84,"slug":85,"count":81,"latest_published_at":86},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
