Red Hat Security Advisory: redis:6 security update
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 Unauthenticated Denial of Service (CVE-2025-48367) * redis: Redis Hyperloglog Out-of-Bounds Write Vulnerability (CVE-2025-32023) 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.
