From: Dan Carpenter Date: Fri, 14 Feb 2014 09:03:13 +0000 (+0300) Subject: mwifiex: memory corruption in mwifiex_tdls_add_vht_capab() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c42c65c1d5863bca54e45ea25ecb24a3def29f59;p=openwrt%2Fstaging%2Fblogic.git 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.
