Rocky Linux administrators should prioritize a new wave of security patches covering MySQL, PostgreSQL, and cluster management utilities. These advisories span multiple operating system releases with important fixes targeting PostgreSQL fifteen through eighteen on version nine systems. Older infrastructure gets moderate database updates while the newest platform receives critical enhancements for fence-agents. Each advisory provides specific CVSS scores so teams can quickly assess which vulnerabilities demand immediate attention.
