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: <1522375625-135679-1-git-send-email-weiyongjun1@huawei.com> (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.
