[$] Scrutinizing bugs found by syzbot

The syzbot
kernel-fuzzing system finds an enormous number of bugs, but, since many
of them may seem to be of a relatively low severity, they have a lower priority
when contending for the attention of developers. A talk
at the recent Linux
Security Summit North America reported on some research that
dug further into the bugs that syzbot has
found; the results are rather worrisome. Rather than a pile of
difficult- or impossible-to-exploit bugs, there are numerous, more serious
problems lurking within.
