Mark Salyzyn b59a23d596 af_key: pfkey_dump needs parameter validation ... commit 37bd22420f856fcd976989f1d4f1f7ad28e1fcac upstream. In pfkey_dump() dplen and splen can both be specified to access the xfrm_address_t structure out of bounds in__xfrm_state_filter_match() when it calls addr_match() with the indexes. Return EINVAL if either are out of range.
