Hi Larry,

in drivers/staging/rtl8188eu/core/rtw_mlme.c:rtw_check_join_candidate there's this code..

1721         /* check ssid, if needed */
1722         if (pmlmepriv->assoc_ssid.Ssid && pmlmepriv->assoc_ssid.SsidLength) {
1723                 if (competitor->network.Ssid.SsidLength != pmlmepriv->assoc_ssid.SsidLength ||
1724                     _rtw_memcmp(competitor->network.Ssid.Ssid, pmlmepriv->assoc_ssid.Ssid, pmlmepriv->assoc_ssid.SsidLength) == false)
1725                         goto exit;
1726         }
1727 

assoc_ssid.Ssid being an array, this comparison against null probably isn't what was intended ?

	Dave
