It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.  You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing to a list; computing set intersection, union and difference; or getting the member with highest ranking in a sorted set.  In order to achieve its outstanding performance, Valkey works with an in-memory dataset. Depending on your use case, you can persist it either by dumping the dataset to disk every once in a while, or by appending each command to a log.  Valkey also supports trivial-to-setup master-slave replication, with very fast non-blocking first synchronization, auto-reconnection on net split and so forth.  Other features include Transactions, Pub/Sub, Lua scripting, Keys with a limited time-to-live, and configuration settings to make Valkey behave like a cache.  You can use Valkey from most programming languages also.\n\nSecurity Fix(es):\n\n* Valkey: Valkey: Data tampering and denial of service via improper null character handling in Lua scripts (CVE-2025-67733)\n\n* valkey: Valkey: Denial of Service via invalid clusterbus packet (CVE-2026-21863)\n\nFor 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.", "severity": [{"type": "CVSS_V3", "score": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:H"}], "affected": [{"package": {"ecosystem": "Rocky Linux:10", "name": "valkey", "purl": "pkg:rpm/rocky-linux/valkey?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:8.0.7-1.el10_1"}], "database_specific": {"yum_repository": "AppStream"}}]}], "references": [{"type": "ADVISORY", "url": "https://errata.rockylinux.org/RLSA-2026:3443"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2442025"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2442026"}], "credits": [{"name": "Rocky Enterprise Software Foundation"}, {"name": "Red Hat"}]}
