{"id":"ALSA-2026:25925","summary":"Important: valkey security update","details":"Valkey 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. 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: use-after-free in unblock client flow may allow remote code execution (CVE-2026-23479)\n  * redis: Remote code execution via use-after-free in Lua scripting (CVE-2026-23631)\n  * redis: RESTORE invalid memory access may allow remote code execution (CVE-2026-25243)\n\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.\n","modified":"2026-07-02T13:30:05.898940637Z","published":"2026-06-15T00:00:00Z","related":["CVE-2026-23479","CVE-2026-23631","CVE-2026-25243"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:25925"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-23479"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-23631"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-25243"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2466780"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2466788"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2466828"},{"type":"ADVISORY","url":"https://errata.almalinux.org/9/ALSA-2026-25925.html"}],"affected":[{"package":{"name":"valkey","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/valkey"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.0.9-1.el9_8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:25925.json"}},{"package":{"name":"valkey-devel","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/valkey-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.0.9-1.el9_8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:25925.json"}}],"schema_version":"1.7.5"}
