From 1399c59fa92984836db90538cf92397fe7caaa57 Mon Sep 17 00:00:00 2001 From: Navid Emamdoost Date: Fri, 4 Oct 2019 14:42:19 -0500 Subject: [PATCH] nl80211: fix memory leak in nl80211_get_ftm_responder_stats 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.
