&gt; Ok, but then the null dereference issue still exists within the context<br>
&gt; of XSM. &nbsp;The options are:<br>
&gt; <br>
&gt; 1) Follow acm_free_domain_ssid(d-&gt;ssid) with d-&gt;ssid = NULL<br>
&gt; (I've tested this and it maintains the desired policy state:<br>
&gt; <br>
&gt; Confict Sets:<br>
&gt; <br>
&gt; &nbsp; &nbsp;c-set 0: &nbsp; &nbsp;00 01 00 01<br>

&gt; Running<br>
&gt; Types: &nbsp; &nbsp; &nbsp; &nbsp; 01 01 00 00<br>

&gt; <br>
&gt; or <br>
&gt; <br>
&gt; 2) Chance acm_free_domain_ssid to pass d instead of ssid and ensure
