Linux Kernel Czar Greg Kroah-Hartman: AI Bug Reports 'Switched from Slop to Legitimate' Overnight — Nobody Knows Why

The Register·medium signal

Linux kernel maintainer Greg Kroah-Hartman reports that AI-generated security bug reports underwent a dramatic quality inflection about a month ago: 'Something happened a month ago, and the world switched. Now we have real reports.' He notes all open source security teams are experiencing this shift simultaneously, but nobody — including the companies submitting them — can explain the improvement. When he tested AI-generated patches, roughly two-thirds were correct (though still needed human cleanup).
