It appears not, if such a bad bug can get through all the way to release.

"Linux" had a bug in which you could log into a system by pressing backspace 28 times a few years ago. And by Linux, I meant GRUB[1], and in turn, (many) Linux systems.

We're comparing Linux and Windows, an operating system that contains 3.5 million files[2] (of course, not just the kernel in this case). That isn't really fair. Code is as perfect as humans can make it, and it certainly does not help that there's so much to take into account.

This GRUB bug you are talking about, is not a kernel problem though; on a side note, I'm going to read on the links you provided as I want to see if encrypted root partitions could also be compromised, I suspect no.

That's not quite on par with this Windows bug, but I take your point.
