Red Hat Security Advisory: mysql security update
MySQL is a multi-user, multi-threaded SQL database server. MySQL is a client/server implementation consisting of a server daemon (mysqld) and many different client programs and libraries. The base package contains the standard MySQL client programs and generic MySQL files. Security Fix(es): * mysql: InnoDB unspecified vulnerability (CPU Apr 2026) (CVE-2026-22004) * mysql: Information Schema unspecified vulnerability (CPU Apr 2026) (CVE-2026-22001) * mysql: Group Replication Plugin unspecified vulnerability (CPU Apr 2026) (CVE-2026-34271) * mysql: Optimizer unspecified vulnerability (CPU Apr 2026) (CVE-2026-22009) * mysql: InnoDB unspecified vulnerability (CPU Apr 2026) (CVE-2026-35237) * mysql: Optimizer unspecified vulnerability (CPU Apr 2026) (CVE-2026-21998) * mysql: Optimizer unspecified vulnerability (CPU Apr 2026) (CVE-2026-22005) * mysql: InnoDB unspecified vulnerability (CPU Apr 2026) (CVE-2026-35238) * mysql: DML unspecified vulnerability (CPU Apr 2026) (CVE-2026-35239) * mysql: Optimizer unspecified vulnerability (CPU Apr 2026) (CVE-2026-22002) * mysql: InnoDB unspecified vulnerability (CPU Apr 2026) (CVE-2026-35236) * mysql: JSON unspecified vulnerability (CPU Apr 2026) (CVE-2026-34308) * mysql: Optimizer unspecified vulnerability (CPU Apr 2026) (CVE-2026-34303) * mysql: Optimizer unspecified vulnerability (CPU Apr 2026) (CVE-2026-35240) * mysql: Optimizer unspecified vulnerability (CPU Apr 2026) (CVE-2026-22017) * mysql: InnoDB unspecified vulnerability (CPU Apr 2026) (CVE-2026-34304) * mysql: Information Schema unspecified vulnerability (CPU Apr 2026) (CVE-2026-22015) * mysql: Group Replication Plugin unspecified vulnerability (CPU Apr 2026) (CVE-2026-34276) * mysql: Group Replication Plugin unspecified vulnerability (CPU Apr 2026) (CVE-2026-34270) 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.

Technical Summary
Red Hat issued a security advisory (RHSA-2026:20693) for MySQL 8.4 on Red Hat Enterprise Linux 10 addressing 19 unspecified vulnerabilities across multiple MySQL components such as InnoDB, Information Schema, Group Replication Plugin, Optimizer, DML, and JSON. Each vulnerability is identified by a CVE number (e.g., CVE-2026-21998, CVE-2026-22001, CVE-2026-34271, among others). The advisory classifies the security impact as moderate and references the Red Hat article for update application instructions. No CVSS scores or detailed vulnerability descriptions are provided in the advisory. The update is available for multiple architectures and variants of Red Hat Enterprise Linux 10 and CodeReady Linux Builder 10.
Potential Impact
The vulnerabilities affect core MySQL components and could potentially impact the confidentiality, integrity, or availability of the database server. However, the advisory does not specify the exact nature or exploitation impact of each vulnerability. The overall security impact is rated as moderate by Red Hat Product Security. There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
A security update for mysql8.4 is available for Red Hat Enterprise Linux 10 and related products. Users should apply the update as per Red Hat's instructions in the advisory RHSA-2026:20693 and the referenced article https://access.redhat.com/articles/11258. Since this is an official Red Hat security advisory with an update available, applying the update is the recommended remediation. Patch status is confirmed by the vendor advisory.
