            <title>[SERVER-32537] Potential use of an uninitialized UUID value during chunk migration</title>

                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The chunk migration startup &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e4405af1fa6d231a792cf62361968915a914fd2e/src/mongo/db/s/migration_source_manager.cpp#L167-L177&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;code&lt;/a&gt; can potentially return a default-constructed UUID value, which will later on be used to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e4405af1fa6d231a792cf62361968915a914fd2e/src/mongo/db/s/migration_source_manager.cpp#L644&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;notify&lt;/a&gt; the shard secondary. Because of this, for collections which do not have UUIDs, we will write some garbage UUID value, which can be misinterpreted.&lt;/p&gt;</description>
