            <title>[SERVER-70365] Fix data race in setting/getting the logical session ID</title>
                <link>https://jira.mongodb.org/browse/SERVER-70365</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The reading thread in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/session/kill_sessions_common.cpp#L52&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;kill_sessions_common.cpp&lt;/a&gt; does acquire the client lock to access the logical session id on opCtx, the writing thread in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/repl/transaction_oplog_application.cpp#L438&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;transaction_oplog_application&lt;/a&gt; does not. As a result, we may have a read after write data race while accessing the logical session id.&lt;/p&gt;

&lt;p&gt;A potential suggestion would be for the writing thread to also acquire the client lock before setting the logical session id.&lt;/p&gt;</description>
