Subject: [PATCH] staging: rtl8188eu: core: rtw_wlan_util.c: Fix for NULL dereference
Date: Mon, 26 Jan 2015 16:39:14 +0100 [thread overview]
Message-ID: <1422286754-3039-1-git-send-email-gmate.amit@gmail.com> (raw)
In rtw_check_bcn_info(), check the return value of kzalloc() before
dereferencing it, to avoid NULL pointer dereference.
