Subject: [PATCH 0/6] libmultipath: check udev* func return value
Date: Tue, 15 Sep 2020 12:38:27 +0800 [thread overview]
Message-ID: <d89bc33d-8e5d-d194-3b26-83ff4d170c5c@huawei.com> (raw)
Hi,
The udev* function may return NULL,and it will be
dereferenced in str* and sscanf func. For example,
there is a coredump caused in add func, which show in
be7a043(commit id) in upstream-queue. We check the
return value to avoid dereference NULL.
