cfg80211: Fix validation of AKM suites
commit 1b9ca0272ffae212e726380f66777b30a56ed7a5 upstream.
Incorrect variable was used in validating the akm_suites array from
NL80211_ATTR_AKM_SUITES. In addition, there was no explicit
validation of the array length (we only have room for
NL80211_MAX_NR_AKM_SUITES).
This can result in a buffer write overflow for stack variables with
arbitrary data from user space. The nl80211 commands using the affected
functionality require GENL_ADMIN_PERM, so this is only exposed to admin
users.
