None. It is at present a bunch of patches. However, most distributions
have pushed out a fixed version by now. On Mangeia it is 2.6-1.1 on
Mageia 6, 2.6-1 on Mageia 5 and 2.6-3 on Mageai Cauldron.
You do not tell us which Linux you are refering to.
Note that 2.4 probably does not have the fix.
But it all depends on your distro.


LINUX:
x@x:~$ which wpa_supplicant
/sbin/wpa_supplicant
x@x:~$ !$ -version
wpa_supplicant -version
wpa_supplicant v2.4

'wpa_supplicant' is not recognized as an internal or external command,
operable program or batch file.

Windows does not use wpa_supplicant. That is an open source wpa program.
It is used by Android, but again it is probably not a "stock" version,
but may well have been altered by the phone manufacturer to include
special features of the wireless chipset they use.
