Subject: [PATCH] nl80211: fix memory leak in nl80211_get_ftm_responder_stats
Date: Fri, 4 Oct 2019 14:42:19 -0500 [thread overview]
Message-ID: <20191004194220.19412-1-navid.emamdoost@gmail.com> (raw)
In nl80211_get_ftm_responder_stats, a new skb is created via nlmsg_new
named msg. If nl80211hdr_put() fails, then msg should be released. The
return statement should be replace by goto to error handling code.
Fixes: 81e54d08d9d8 ("cfg80211: support FTM responder configuration/statistics")
