If all bugs are security flaws, then the security system in Linux is worthless.

While I think this is technically correct that the majority bugs have a security impact, that is not necessarily obvious when the bug is discovered, but that the conclusion is not useful for any practical decision making purpose. Whether you have a thousand security-critical bugs or a hundred doesn't matter because the attacker only needs one. Every system has them with greater or lesser levels of investigation as to whether the bugs are security relevant and disclosure of same. I believe, but cannot prove, that it is impossible to build a modern OS kernel with all the services it is expected to provide and not have security critical bugs. I don't think it is cause for giving up, even though as you said, the presence of bugs often allows security systems to be bypassed.
