Description Joel Chamberlain 2026-10-22 19:05:32 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Incomplete cleanup vulnerability in Apache Tomcat could cause TLS 1.3 connections to fail intermittently.

Users are recommended to upgrade to version 11.0.27, 10.1.61 or 9.0.123, which fix the issue.
