netfilter: x_tables: avoid out-of-bounds reads in xt_request_find_{match|target}
commit da17c73b6eb74aad3c3c0654394635675b623b3e upstream.
It looks like syzbot found its way into netfilter territory.
Issue here is that @name comes from user space and might
not be null terminated.
Out-of-bound reads happen, KASAN is not happy.
v2 added similar fix for xt_request_find_target(),
as Florian advised.
