medium Nessus Plugin ID 331750

Synopsis

The remote Red Hat host is missing one or more security updates for mariadb10.11.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:49522 advisory.

MariaDB is a community developed fork from MySQL - a multi-user, multi-threaded SQL database server. It is a client/server implementation consisting of a server daemon (mariadbd) and many different client programs and libraries. The base package contains the standard MariaDB/MySQL client programs and utilities.

Security Fix(es):

* mariadb: MariaDB Server: Arbitrary code execution via wsrep_notify_cmd (CVE-2026-49261)

* mariadb: Arbitrary Code Execution via improper parameter validation during State Snapshot Transfer (CVE-2026-44168)

* mariadb: Arbitrary shell command execution via improper sanitization in CONNECT engine (CVE-2026-44170)

* mariadb: mbstream: Unauthorized file creation via path traversal (CVE-2026-44171)

* mariadb: Arbitrary code execution via improper parameter validation during SST (CVE-2026-48163)

* mariadb: Arbitrary code execution via global system variable manipulation by a high-privileged user (CVE-2026-48165)

* mariadb: MariaDB: Privilege bypass allows unauthorized file write via subqueries (CVE-2026-44173)

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL mariadb10.11 package based on the guidance in RHSA-2026:49522.
