TuxCare keeps you ahead of threats by proactively tracking and patching new CVEs impacting Apache Kafka. View all security fixes available to date here.

Keep Running.
Skip the Risks.

Upgrading end-of-life open-source runtimes, libraries, and
applications can be disruptive, resource-intensive, and costly.

TuxCare’s ELS keeps your legacy and EOL
components secure, compliant, and stable – without
the risks of costly upgrades.

What Does Endless Lifecycle Support Include?

Rapid CVE Response

Rapid SLA-backed security patches for Apache Kafka for as long as you need

Complete Coverage

Security fixes for both direct and transitive dependencies in Apache Kafka AT NO EXTRA COST

Preserved Compatibility

Extensively tested updates designed to work flawlessly with your existing code

Seamless Integration

Plug-and-play integration with your existing workflows and CI/CD pipelines

Secure Distribution

Signed, tamper-proof Apache Kafka security updates delivered from trusted, TuxCare-hosted repositories

Trusted Support

24/7 expert assistance with Apache Kafka vulnerability triage, security patch requests, and troubleshooting

Secure Every Layer of Your OSS
Dependency Tree for the Long Run

End-of-life risk rarely lives in your top-level packages. It hides in the transitive
dependencies woven throughout your open-source stack.

When one of those libraries becomes vulnerable, every downstream component
must be rebuilt and validated.

TuxCare automates this entire process – tracking vulnerable EOL
libraries, applying security fixes, and rebuilding dependent components
– ensuring your full dependency chain stays secure and stable.

How Does It Work?

1

We onboard new projects and enable 24/7 automated CVE tracking – monitoring the NVD, vendor, and GitHub security advisories, and other sources.

2

Once CVEs are detected, we backport upstream fixes using algorithmic and AI-assisted automation, with expert validation to ensure accuracy.

3

Patches are compiled in a binary format, extensively tested (for integrity, functionality, and regression), signed, and deployed to ELS repositories.

4

Your package managers, build tools, or orchestrators check for updates, then automatically pull and install them.

Frequently Asked Questions

ELS for Apache Kafka provides security patches and selected bug fixes for Kafka releases the Apache Kafka project no longer maintains. Patched Kafka artifacts are delivered from a TuxCare Maven repository, so applications built on those versions can keep receiving security fixes.

Apache Kafka 2.8.2, 3.2.2, 3.2.3 and 3.7.1. These builds also cover Spring for Apache Kafka applications that indirectly pull in the client. Other versions can be discussed with TuxCare's sales team.

Not long. The Kafka community generally maintains only the most recent releases, so a version can stop getting fixes within a year or two of shipping. Many organizations run Kafka clusters and clients far longer than that, which leaves known CVEs open on core data infrastructure.

One well-known example is CVE-2023-25194, where a crafted SASL JAAS configuration in Kafka Connect could lead to JNDI-based remote code execution in versions 2.3.0 through 3.3.2. Issues like that sit on infrastructure that handles sensitive data, so leaving them open is hard to justify in an audit.

Configure your TuxCare credentials in Maven or Gradle, add the TuxCare repository, and replace your Kafka dependency versions with TuxCare-maintained ones, such as 3.2.3.tuxcare.1. Artifact versions are browsable in TuxCare's Nexus after you sign in, and you can proxy the repository through your own Artifactory or Nexus.

TuxCare targets 14 days from public disclosure for critical and high vulnerabilities, 60 days for medium and 90 days for low. CycloneDX VEX documents for Java packages show which CVEs each patched build resolves.

ELS for Apache Kafka is delivered as Maven artifacts for use in Maven or Gradle builds. If you need coverage for a broker distribution or a specific deployment model, confirm the scope with TuxCare's sales team before relying on it.
