You've fuzzed every version and you only found a few bugs? LOL. Here are 6700 bugs currently categorized in 14.04.

To be clear: just because there's a bug doesn't mean there's an exploit for it. So no need to panic about 6700 bugs. To believe there are only a few bugs is just wrong.
Are you referring one rather popular distro that didn't (or doesn't) offer kernel updates at the "default" level?
No, more of a general apathy or complacency towards patching. As for that distro, it's helpful to remember the old saying "Linux assumes you know exactly what you're doing."
