From c42c65c1d5863bca54e45ea25ecb24a3def29f59 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 14 Feb 2014 12:03:13 +0300 Subject: [PATCH] mwifiex: memory corruption in mwifiex_tdls_add_vht_capab() There is a typo here because the names are confusingly similar. The intent was sizeof(struct ieee80211_vht_cap) (size 12) but sizeof(struct ieee80211_ht_cap) (size 32) was used. Anway, it's cleaner to just specify the variable instead of the type.
