Hi Deepak, As Israel mentioned, the core Apache Kafka components do not have any dependencies on log4j2. The only CVE that core Apache Kafka got impacted is CVE-2021-4104. You can check the official announcement for the mitigation methods here: https://kafka.apache.org/cve-list
For the log4j 2.x preview, I don't suggest applying to the production environment. After all, the PR haven't completed code reviewed yet. But you can try it on staging environment, and welcome to report any issue to us. Thank you.
