Subject: [patch] target/iscsi: double free in lio_target_tiqn_addtpg()
Date: Tue, 13 Dec 2016 12:27:04 +0000 [thread overview]
Message-ID: <20161213122703.GB7519@elgon.mountain> (raw)
This iscsit_tpg_add_portal_group() function is only called from
lio_target_tiqn_addtpg(). Both functions free the "tpg" pointer on
error so it's a double free bug. The memory is allocated in the caller
so it should be freed in the caller and not here.
Fixes: e48354ce078c ("iscsi-target: Add iSCSI fabric support for target v4.1")
