Subject: [PATCH AUTOSEL 4.14 104/371] staging: r8822be: check kzalloc return or bail
Date: Thu, 16 Jan 2020 12:19:36 -0500 [thread overview]
Message-ID: <20200116172403.18149-47-sashal@kernel.org> (raw)
In-Reply-To: <20200116172403.18149-1-sashal@kernel.org>
From: Nicholas Mc Guire <hofrat@osadl.org>
[ Upstream commit e4b08e16b7d9d030b6475ef48f94d734a39f3c81 ]
The kzalloc() in halmac_parse_psd_data_88xx() can fail and return NULL
so check the psd_set->data after allocation and if allocation failed
return HALMAC_CMD_PROCESS_ERROR.
