+=head2 [CVE-2025-40909] Perl threads have a working directory race condition where file operations may target unintended paths
+
+Perl thread cloning had a working directory race condition where file

+handle.
+
+This problem was discovered by Vincent Lefèvre via
+[L<GH #23010|https://github.com/Perl/perl5/issues/23010>] and assigned
+[L<CVE-2025-40909|https://lists.security.metacpan.org/cve-announce/msg/30017499/>]
+by the L<CPAN Security Group|https://security.metacpan.org/>.
+
+Fixes were provided via [L<GH #23019|https://github.com/Perl/perl5/pull/23019>]
+and [L<GH #23361|https://github.com/Perl/perl5/pull/23361>].
+

+
+There are no changes intentionally incompatible with 5.38.4.  If any exist,
+they are bugs, and we request that you submit a report.  See L</Reporting

+=head1 Documentation
+
+=head2 Changes to Existing Documentation
+
+We have attempted to update the documentation to reflect the changes listed in
+this document.  If you find any we have missed, open an issue at
+L<https://github.com/Perl/perl5/issues>.
+
+=head1 Testing
+
+Tests were added and changed to reflect the other additions and changes in this
+release.
+
+=head1 Acknowledgements
+
+Perl 5.38.5 represents approximately 4 months of development since Perl 5.38.4
+and contains approximately 3,300 lines of changes across 46 files from 8
+authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 1,100 lines of changes to 7 .pm, .t, .c and .h files.
+
+Perl continues to flourish into its fourth decade thanks to a vibrant community
+of users and developers.  The following people are known to have contributed
+the improvements that became Perl 5.38.5:
+
+James E Keenan, Karen Etheridge, Leon Timmermans, Lukas Mai, Philippe Bruhat
+(BooK), Richard Leach, Steve Hay, Thibault Duponchelle.
+
+The list above is almost certainly incomplete as it is automatically generated
+from version control history.  In particular, it does not include the names of
+the (very much appreciated) contributors who reported issues to the Perl bug
+tracker.
+
+Many of the changes included in this version originated in the CPAN modules
+included in Perl's core.  We're grateful to the entire CPAN community for
+helping Perl to flourish.
+
+For a more complete list of all of Perl's historical contributors, please see
+the F<AUTHORS> file in the Perl source distribution.
+
+=head1 Reporting Bugs
+
+If you find what you think is a bug, you might check the perl bug database at
+L<https://github.com/Perl/perl5/issues>.  There may also be information at
+L<http://www.perl.org/>, the Perl Home Page.
+
+If you believe you have an unreported bug, please open an issue at
+L<https://github.com/Perl/perl5/issues>.  Be sure to trim your bug down to a
+tiny but sufficient test case.
+
+If the bug you are reporting has security implications which make it
+inappropriate to send to a public issue tracker, then see
+L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION> for details of how to
+report the issue.
+
+=head1 Give Thanks
+
+If you wish to thank the Perl 5 Porters for the work we had done in Perl 5, you
+can do so by running the C<perlthanks> program:
+
+    perlthanks
+
+This will send an email to the Perl 5 Porters list with your show of thanks.
