            <title>[SERVER-47846] CollMod (_collModInternal) unsafely accesses an IndexCatalogEntry that is destructed in an onRollback handler</title>
                <link>https://jira.mongodb.org/browse/SERVER-47846</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;_collModInternal has a cmrNew variable that is used in a writeConflictRetry loop, but initialized before the loop begins. Usage of cmrNew must be very careful not to access memory that can become invalid (freed) after an onRollback call caused by a WriteConflictException. After &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-9306&quot; title=&quot;Ability to temporarily forbid query optimizer from using index (&amp;quot;invisible index&amp;quot;)&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-9306&quot;&gt;&lt;del&gt;SERVER-9306&lt;/del&gt;&lt;/a&gt;, we &lt;a href=&quot;https://github.com/mongodb/mongo/blob/99d02eb3255acf527cd11af3102a2274b87a1486/src/mongo/db/catalog/coll_mod.cpp#L439&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;try to access cmrNew.idx (the unsafe pointer)&lt;/a&gt; before &lt;a href=&quot;https://github.com/mongodb/mongo/blob/99d02eb3255acf527cd11af3102a2274b87a1486/src/mongo/db/catalog/coll_mod.cpp#L444&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;initializing it again&lt;/a&gt; in the writeConflictRetry loop. The old code, prior to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-9306&quot; title=&quot;Ability to temporarily forbid query optimizer from using index (&amp;quot;invisible index&amp;quot;)&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-9306&quot;&gt;&lt;del&gt;SERVER-9306&lt;/del&gt;&lt;/a&gt;, did not make this mistake: &lt;a href=&quot;https://github.com/mongodb/mongo/blob/17edea396d470d0ddc258674feba030ffafbffe8/src/mongo/db/catalog/coll_mod.cpp#L384-L398&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;the access used to be after initializing the pointer&lt;/a&gt;, so the pointer was safe for use at that point.&lt;/p&gt;</description>
