Subject: [NETFILTER 05/10]: nfnetlink_log: fix use after free
Date: Sun, 4 Mar 2007 21:20:04 +0100 (MET) [thread overview]
Message-ID: <20070304201912.28582.29134.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070304201906.28582.51903.sendpatchset@localhost.localdomain>
[NETFILTER]: nfnetlink_log: fix use after free
Paranoia: instance_put() might have freed the inst pointer when we
spin_unlock_bh().
