            <title>[SERVER-75369] Fix the overflow of total possible enumeration count in LockstepOr enumeration strategy</title>
                <link>https://jira.mongodb.org/browse/SERVER-75369</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There&apos;s a count variable for computing the total possible enumeration of a $or query.&lt;/p&gt;

&lt;p&gt;This &lt;a href=&quot;https://github.com/10gen/mongo/blob/c5519fd438f2880e7a80fe60cdb3ab3e5dc0712a/src/mongo/db/query/plan_enumerator.cpp#L1717&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;variable&lt;/a&gt; could overflow if the $or is large enough, e.g. a machine generated $or with 200 predicates. Each predicate has two possible enumerations. The size_t count would overflow with a value of 2^200.&lt;/p&gt;

&lt;p&gt;While calculating the count, we can bail out early if the count reaches the limit for $or, which is 10 by default.&lt;/p&gt;</description>
