The interview was originally posted in french only on linuxfr.org (Linux-related site in French), but the interviewer was nice enough to post the original english version.

The exploit in question is called "Cheddar Bay" and had been discussed on HN here: http://news.ycombinator.com/item?id=709869.

The title is misleading: there will definitely be more linux exploits.

fixed, thanks (the title was originally: "Interview with Brad Sprengler, author of the last Linux 0day exploit"). Sorry for my poor english skills.
