Red Hat Security Advisory: redis:7 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: Lua library commands may lead to integer overflow and potential RCE (CVE-2025-46817) * Redis: Redis: Authenticated users can execute LUA scripts as a different user (CVE-2025-46818) * Redis: Redis is vulnerable to DoS via specially crafted LUA scripts (CVE-2025-46819) * Redis: Redis Lua Use-After-Free may lead to remote code execution (CVE-2025-49844) 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.

Technical Summary
This advisory covers four distinct vulnerabilities in Redis 7 related to its Lua scripting capabilities: CVE-2025-46817 involves integer overflow in Lua library commands potentially leading to remote code execution; CVE-2025-46818 allows authenticated users to execute Lua scripts as a different user, effectively a privilege escalation; CVE-2025-46819 enables denial of service through specially crafted Lua scripts; and CVE-2025-49844 is a Lua use-after-free vulnerability that may lead to remote code execution. Red Hat has released updated Redis 7 packages for Red Hat Enterprise Linux 9.6 and related extended update support versions to fix these issues.
Potential Impact
The vulnerabilities collectively allow for potential remote code execution, privilege escalation, and denial of service against Redis instances running on affected Red Hat Enterprise Linux 9 systems. Exploitation requires authenticated access for some issues, while others may be triggered by crafted Lua scripts. These flaws could compromise the confidentiality, integrity, and availability of Redis services.
Mitigation Recommendations
Red Hat has released updated Redis 7 packages (version 7.2.11-1.module+el9.6.0+...) that address these vulnerabilities. Users should apply the official security update provided by Red Hat for their specific Red Hat Enterprise Linux 9 variant as detailed in advisory RHSA-2025:19345. Patch status is confirmed as fixed in these updated packages. No additional mitigations beyond applying the update are specified.
