CVE-2026-101788

A flaw was found in MySQL Server and MySQL Cluster within the Server Components Services. This vulnerability allows an unauthenticated remote attacker with network access via multiple protocols to cause a Denial of Service (DoS). A successful attack can cause the database server to hang or repeatedly crash.

This vulnerability is assessed as having Moderate impact for Red Hat deployments because, while an unauthenticated network attacker can trigger service unavailability, successful execution requires high attack complexity and cannot be leveraged to expose or modify data. In typical enterprise environments, database services are isolated within secured network perimeters rather than exposed to untrusted external traffic, which significantly limits practical exploitation opportunities.
