Red Hat Product Errata RHSA-2026:64823 - Security Advisory Issued: 2026-09-08 Updated: 2026-09-08 RHSA-2026:64823 - Security Advisory Overview Updated Packages Synopsis Important: redis:6 security update Type/Severity Security Advisory: Important Red Hat Lightspeed patch analysis Identify and remediate systems affected by this advisory. View affected systems Topic An update for the redis:6 module is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. 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 Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log. Security Fix(es): redis: Redis: Remote Code Execution via specially crafted RESTORE payload (CVE-2026-66373) redis: Redis: Arbitrary code execution via TLS pending-data list use-after-free (CVE-2026-81934) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
