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.
