Description OSIDB Bzimport 2026-10-21 19:33:44 UTC 
Apache Traffic Server can crash with a null pointer dereference when a client POST request is torn down via half-close while a chunked origin response is being reparsed from a reentrant write-ready callback, a timing-dependent race introduced by the CVE-2021-32564 flow-control backports.



This issue affects Apache Traffic Server: 9.2.15, 10.1.4, 10.2.0.



Users are recommended to upgrade to version 9.2.16, 10.1.5, or 10.2.1, which fix the issue.
