[UPDATE] [mittel] Red Hat Enterprise Linux (Gatekeeper): Mehrere Schwachstellen ermöglichen Denial of Service

A new security advisory has been published regarding multiple vulnerabilities in Red Hat Enterprise Linux (RHEL) that could enable Denial of Service (DoS) attacks. The advisory, identified as WID-SEC-2025-0606, was issued by certbund and falls under the purview of the Digital Markets Act (DMA) framework. These vulnerabilities, if exploited, could disrupt system availability.

Organizations utilizing affected versions of Red Hat Enterprise Linux are primarily impacted. This is particularly relevant for entities designated as gatekeepers under the DMA, as well as any other organizations in sectors where high system availability is critical for compliance, such as financial services, telecommunications, and essential service providers.

Compliance teams should immediately coordinate with their IT security counterparts to identify all systems running the affected RHEL versions. The next step is to assess the risk exposure and apply the relevant security patches provided by Red Hat without delay. Teams should also review and potentially update incident response plans to address potential DoS scenarios, ensuring continued adherence to DMA resilience and security obligations.
