RHEL 9 : redis:7 (RHSA-2026:69521)

high Nessus Plugin ID 348597

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for redis:7.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:69521 advisory.

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: Redis: Remote Code Execution via specially crafted RESTORE payload (CVE-2026-66373)

* redis: Redis: Denial of Service via Out-of-Bounds Read in Cluster Bus (CVE-2026-72568)

* redis: Redis: Arbitrary code execution via TLS pending-data list use-after-free (CVE-2026-81934)

* redis: Redis: Out-of-bounds read via crafted cluster bus packets (CVE-2026-92925)

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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
