From 040bdf713d2bec8235f1af705e2d13da5d9baec8 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 10 Aug 2011 19:00:33 -0600 Subject: cfg80211: fix a crash in nl80211_send_station mac80211 leaves sinfo->assoc_req_ies uninitialized, causing a random pointer memory access in nl80211_send_station. Instead of checking if the pointer is null, use sinfo->filled, like the rest of the fields. Signed-off-by: Felix Fietkau Signed-off-by: John W.
