Subject: [PATCH 2/8] netfilter: ipset: off by one in ip_set_nfnl_get_byindex()
Date: Mon, 27 Oct 2014 22:38:01 +0100 [thread overview]
Message-ID: <1414445887-5108-3-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1414445887-5108-1-git-send-email-pablo@netfilter.org>
From: Dan Carpenter <dan.carpenter@oracle.com>
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.
