RHSA-2026:86676 - Security Advisory

  • Overview

Synopsis

Important: Streams for Apache Kafka 3.2.2 release and security update

Type/Severity

Security Advisory: Important

Topic

Streams for Apache Kafka 3.2.2 is now available from the Red Hat Customer Portal.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

Red Hat Streams for Apache Kafka, based on the Apache Kafka project, offers a distributed backbone that allows microservices and other applications to share data with extremely high throughput and extremely low latency.

This release of Red Hat Streams for Apache Kafka 3.2.2 serves as a replacement for Red Hat Streams for Apache Kafka 3.2.1, and includes security and bug fixes, and enhancements.

Security Fix(es):
