ALSA-2026:23229 — Important: redis security update

Affected: AlmaLinux:9: redis, AlmaLinux:9: redis-devel, AlmaLinux:9: redis-doc

Redis 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. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log.

Security Fix(es):

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

For 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.

BIT-keydb-2026-25243 — redis-server RESTORE invalid memory access may allow remote code execution

Affected: Bitnami: keydb

Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3.

OESA-2026-2237 — redis security update

Affected: openEuler:24.03-LTS: redis, openEuler:24.03-LTS-SP1: redis, openEuler:24.03-LTS-SP3: redis, openEuler:20.03-LTS-SP4: redis, openEuler:22.03-LTS-SP4: redis

Redis is an advanced key-value store. It is often referred to as a dattructure server since keys can contain strings, hashes ,lists, sets anorted sets. Security Fix(es):

When a blocked client is evicted while re-executing a blocked command, an authenticated user may trigger a use-after-free and potentially lead to remote code execution.

The problem exists in Redis `7.2` or newer.(CVE-2026-23479)

An authenticated user may exploit the synchronization mechanism of the master-replica and trigger a use-after-free vulnerability, potentially leading to remote code execution. The bug affects only replicas that are configured, or may be configured with `replica-read-only` disabled, and exists in all versions of Redis with Lua scripting.(CVE-2026-23631)

A vulnerability in the Redis RESTORE command allows an authenticated user to trigger an invalid memory access via a specially crafted serialized payload, potentially resulting in remote code execution. Successful exploitation could allow an attacker with authenticated access to execute arbitrary code in the context of the Redis server, potentially leading to full compromise of the affected system, data exfiltration, or service disruption. This problem affects all Redis versions.(CVE-2026-25243)
