In the Linux kernel, the following vulnerability has been resolved:

wifi: mwifiex: Fix memcpy() field-spanning write warning in mwifiex_config_scan()

Replace one-element array with a flexible-array member in `struct
mwifiex_ie_types_wildcard_ssid_params` to fix the following warning
on a MT8173 Chromebook (mt8173-elm-hana):

[ 356.775250] ------------[ cut here ]------------
[ 356.784543] memcpy: detected field-spanning write (size 6) of single field 'wildcard_ssid_tlv->ssid' at drivers/net/wireless/marvell/mwifiex/scan.c:904 (size 1)
[ 356.813403] WARNING: CPU: 3 PID: 742 at drivers/net/wireless/marvell/mwifiex/scan.c:904 mwifiex_scan_networks+0x4fc/0xf28 [mwifiex]

The '(size 6)' above is exactly the length of the SSID of the network
this device was connected to. The source of the warning looks like:

ssid_len = user_scan_in->ssid_list[i].ssid_len;
[...]
memcpy(wildcard_ssid_tlv->ssid,
user_scan_in->ssid_list[i].ssid, ssid_len);

There is a #define WILDCARD_SSID_TLV_MAX_SIZE that uses sizeof() on this
struct, but it already didn't account for the size of the one-element
array, so it doesn't need to be changed.
