Subject: [PATCH] cfg80211: Fix memory leak in cfg80211_inform_single_bss_data
Date: Sun, 27 Oct 2019 13:04:46 -0500 [thread overview]
Message-ID: <20191027180447.8998-1-navid.emamdoost@gmail.com> (raw)
In the implementation of cfg80211_inform_single_bss_data() the allocated
memory for ies is leaked in case of an error. Release ies if
cfg80211_bss_update() fails.
Fixes: 06aa7afaaa21 ("cfg80211: add cfg80211_inform_bss")
