Hi Fabio,
I've just briefly looked at that c7e88ecbe328. I have no time to dig it deeper
but at a first look it seems that the following line is the culprit:
kfree(&pmlmepriv->assoc_req);
It should be:
kfree(pmlmepriv->assoc_req);
The second line frees the memory location whose address is saved in assoc_rec;
the first line instead frees assoc_req itself.
Regards,
Fabio
