Florian Westphal e18939176e netfilter: xt_nfacct: don't assume acct name is null-terminated 
[ Upstream commit bf58e667af ]

BUG: KASAN: slab-out-of-bounds in .. lib/vsprintf.c:721
Read of size 1 at addr ffff88801eac95c8 by task syz-executor183/5851

 string+0x231/0x2b0 lib/vsprintf.c:721

 nfacct_mt_checkentry+0xd2/0xe0 net/netfilter/xt_nfacct.c:41
 xt_check_match+0x3d1/0xab0 net/netfilter/x_tables.c:523

nfnl_acct_find_get() handles non-null input, but the error
printk relied on its presence.
