            <title>[CDRIVER-2238] Race in mongoc_client_kill_cursor</title>

                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;mongoc_client_kill_cursor gets a server description from the topology, then continues to access the server description after it has unlocked the topology. In pooled mode, the server description could be freed by a topology change while mongoc_client_kill_cursor holds a reference to it.&lt;/p&gt;</description>

&lt;p&gt;Message:&lt;a href=&quot;https://jira.mongodb.org/browse/CDRIVER-2238&quot; title=&quot;Race in mongoc_client_kill_cursor&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CDRIVER-2238&quot;&gt;&lt;del&gt;CDRIVER-2238&lt;/del&gt;&lt;/a&gt; race in mongoc_client_kill_cursor&lt;/p&gt;

&lt;p&gt;Once the topology mutex is unlocked, it isn&apos;t safe to use a server&lt;br/&gt;
description from the topology: the server description could be freed by&lt;br/&gt;
a topology change before mongoc_client_kill_cursor accesses its server&lt;br/&gt;
id. I had apparently begun to make this thread-safe a while ago but&lt;br/&gt;
didn&apos;t finish the job until now.&lt;br/&gt;
