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* redis: Redis: Remote Code Execution via specially crafted RESTORE payload (CVE-2026-66373)\n\n* valkey: Valkey: Remote code execution via use-after-free in stream deserialization (CVE-2026-63639)\n\n* valkey: Valkey: Remote code execution via TLS pending-data processing use-after-free (CVE-2026-56684)\n\nBug Fix(es) and Enhancement(s):\n\n* [Tracker] Rebase valkey to 8.0.10 (JIRA:Rocky Linux-216778)\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:U/C:H/I:H/A:H"}], "affected": [{"package": {"ecosystem": "Rocky Linux:9", "name": "valkey", "purl": "pkg:rpm/rocky-linux/valkey?distro=rocky-linux-9&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:8.0.10-1.el9_8"}], "database_specific": {"yum_repository": "AppStream"}}]}], "references": [{"type": "ADVISORY", "url": "https://errata.rockylinux.org/RLSA-2026:64807"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2506985"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2517906"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2517907"}, {"type": "ADVISORY", "url": "https://access.redhat.com/errata/RHSA-2026:64807"}], "credits": [{"name": "Rocky Enterprise Software Foundation"}, {"name": "Red Hat"}], "database_specific": {"license": "CC-BY-4.0", "license_url": "https://creativecommons.org/licenses/by/4.0/", "source_advisory": "RHSA-2026:64807"}}
