-Subject: [PATCH] brcmfmac: avoid potential stack overflow in
- brcmf_cfg80211_start_ap()
-
-User-space can choose to omit NL80211_ATTR_SSID and only provide raw
-IE TLV data. When doing so it can provide SSID IE with length exceeding
-the allowed size. The driver further processes this IE copying it
-into a local variable without checking the length. Hence stack can be
-corrupted and used as exploit.
