Subject: [PATCH -next] tipc: fix possible memory leak in tipc_udp_enable()
Date: Sat, 10 Sep 2016 00:56:55 +0000	[thread overview]
Message-ID: <1473469015-6180-1-git-send-email-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1@huawei.com>

'ub' is malloced in tipc_udp_enable() and should be freed before
leaving from the error handling cases, otherwise it will cause
memory leak.

Fixes: ba5aa84a2d22 ("tipc: split UDP nl address parsing")
