Subject: [PATCH net-next] cfg80211: fix possible memory leak in regdb_query_country()
Date: Fri, 30 Mar 2018 02:07:05 +0000	[thread overview]
Message-ID: <> (raw)

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