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.

Security Fix(es):

  • redis: use-after-free in unblock client flow may allow remote code execution (CVE-2026-23479)

  • redis: Remote code execution via use-after-free in Lua scripting (CVE-2026-23631)

  • redis: RESTORE invalid memory access may allow remote code execution (CVE-2026-25243)
