That's the list of bugs originating in 2015. You need to go back further
to see some of the fun ones still present (CVE-2013-7445 for example)

There are a bunch of those ignored in Bugzilla for years. I think the
ones for the mainstream file systems have all been tackled but things
like reiserfs don't survive fuzzing too well, which is a problem if your
distribution naïvely builds in automounting support for people rooting
your box via USB stick.
