[PATCH 2/8] netfilter: ipset: off by one in ip_set_nfnl_get_byindex()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

The ->ip_set_list[] array is initialized in ip_set_net_init() and it
has ->ip_set_max elements so this check should be >= instead of >
otherwise we are off by one.
