Tech GuruQuick Answer
Red Hat published RHSA-2026:75674 and RHSA-2026:75673 for RHEL 8 and RHEL 9 MariaDB Connector/C packages. Match entitled systems to the advisory scope, install mariadb-connector-c 3.1.11-3.el8_10 / 3.2.6-2.el9_8, validate dependent operations, and retain change evidence.
Validate MariaDB Connector/C Scope And Apply The Red Hat Fix
What to do now: Inventory RHEL 8 and RHEL 9 MariaDB Connector/C packages, confirm the exact entitled branch and installed build, apply the advisory-listed content, validate representative services, and document exceptions.

What Changed
Red Hat published supported MariaDB Connector/C replacement content for the advisory-listed CVEs and product branches.
What To Validate Now
- Inventory. Locate RHEL 8 and RHEL 9 MariaDB Connector/C packages; record the installed build, repository and entitlement, owner, exposure, dependencies, and maintenance group.
- Establish applicability. Compare every system with the product and package relationships in RHSA-2026:75674 and RHSA-2026:75673. Do not infer applicability from the component name or CVSS rating alone.
- Remediate. Install mariadb-connector-c 3.1.11-3.el8_10 / 3.2.6-2.el9_8 from the supported Red Hat channel for the exact branch.
- Validate. Confirm the installed package or image digest, exercise representative MariaDB Connector/C functions and recovery paths, monitor for regressions, and record the result.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Test database authentication, TLS, connection pooling, failover, and dependent applications against the updated connector for the installed RHEL branch. Preserve pre-change versions, logs, installation output, validation evidence, and any rollback decision.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
