Synopsis
Important: redis:6 security update
Type/Severity
Security Advisory: Important
Red Hat Lightspeed patch analysis
Identify and remediate systems affected by this advisory.
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.
