Pragaspathi Thilagaraj 6cf025f727 qcacld-3.0: Fix possible heap overflow in lim_update_ext_cap_ie ... In the function lim_process_set_default_scan_ie_request, memory of MAX_DEFAULT_SCAN_IE_LEN (2048) is allocated for local_ie_buf. This local_ie_buf accommodates the ie data and also the ext capabilities. If the local_ie_len, that is used to copy the ie_data to local_ie_buf is greater than MAX_DEFAULT_SCAN_IE_LEN(2048) - (DOT11F_IE_EXTCAP_MAX_LEN(15) + EXT_CAP_IE_HDR_LEN(2)), then heap overflow could occur. Validate the MAX_DEFAULT_SCAN_IE_LEN against the difference between MAX_DEFAULT_SCAN_IE_LEN and sum of EXT_CAP_IE_HDR_LEN and DOT11F_IE_EXTCAP_MAX_LEN.
