-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-3d18a65cc4 2026-07-31 00:54:29.804769+00:00 --------------------------------------------------------------------------------
Name : valkey Product : Fedora 44 Version : 9.0.5 Release : 1.fc44 URL : https://valkey.io Summary : A persistent key-value database Description : 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.

Valkey 9.0.5 - Released Tue 21 July 2026 Upgrade urgency SECURITY: This release includes security fixes we recommend you apply as soon as possible. Security Fixes CVE-2026-56684: Fix a use-after-free in TLS connection handling that could allow an authenticated client to achieve remote code execution using CLIENT KILL (#4234) CVE-2026-63639: Reject corrupt stream RDB files containing a shared NACK across consumers, which could allow remote code execution. Reported by @z0v3r1n and @lifip.

the connection to the old primary is disconnected by @lukepalmer (#4068) Fix underestimation of client output buffer memory when replies reference shared objects, so buffer limits are enforced correctly by @dvkashapov (#3306) Fix a crash on ARM/aarch64 caused by memory-ordering races in the IO thread job queue by @jjuleslasarte (#3878) Fix a crash when active hash field expiration leaves a single entry in a large expiration time-bucket by @ranshid (#3950) Fix a file descriptor leak when a blocking connection attempt, such as MIGRATE to an unreachable host, times out by @madolson (#3541) Fix a potential crash from a dangling slot migration job reference when the migration client is reset by @murphyjacob4 (#3554) Remove cached EVAL scripts when their scripting engine is unregistered, preventing dangling engine references by @eifrah-aws (#3503) Fix a memory leak in GEOSEARCH BYPOLYGON when argument parsing fails, such as on an invalid COUNT by @bandalgomsu (#3568) Fix a crash when

reading shard IDs past their fixed-length buffer by @enjoy-binbin (#3942) Fix undefined behavior in the failover delay calculation when cluster-node- timeout is set below 30 milliseconds by @enjoy-binbin (#3941) Reject zipmap RESTORE payloads with overflowing length fields that could cause out-of-bounds access on 32-bit builds by @madolson (#3920) Reject NAN scores in listpack- and ziplist-encoded sorted sets on RDB/RESTORE load, preventing a later crash on skiplist conversion by @madolson (#3921) Fix a startup crash on 32-bit systems with 64-bit time_t, such as Alpine 3.23, caused by time value formatting mismatches by @chenshi5012 (#3787) Fix corrupted client replies when IO threads are enabled, caused by a race between in-flight writes and reply buffer reuse by @nanyan0312 (#4060) COMMAND INFO in RESP3 now returns the subcommands field as an Array instead of a Set for commands without subcommands by @rickrams (#3939) The dual-channel replication RDB
