"possible deadlock in handle_rx" is now marked as fixed with
"vhost_net: add missing lock nesting notation".
"KASAN: use-after-free Read in pppol2tp_connect (3)" is marked as
fixed with "l2tp: fix races in tunnel creation".
"KASAN: use-after-free Read in __list_add_valid (5)" is still open.

Though, there are still 182 open bugs on dashboard:
https://syzkaller.appspot.com/

80+ have reproducers and happened last time recently enough. Few
dozens without reproducers, but as history shows ~2/3 of them are
fixable. Part of the remaining ones is probably fixed, but nobody told
syzbot about the fixes. Part is probably still unfixed but happen
episodically.
