CVE Alert: CVE-2025-59215 – Microsoft – Windows Server 2025 (Server Core installation)

Risk verdict

Why this matters

Most likely attack path

Who is most exposed

Detection ideas

• Monitor for memory corruption crashes or bluescreens linked to graphics subsystem modules.
• Look for anomalous process token elevation events and unexpected privilege changes from graphics-related processes.
• Inspect memory dumps and event logs for use-after-free indicators in graphics rendering pipelines.
• Correlate surges in local privilege escalation attempts with conditional access or MFA failures.

Mitigation and prioritisation

• Apply the vendor patch as soon as available; verify deployment via change-control and patch inventory.
• Enforce least-privilege for services and restrict high-privilege processes from loading graphics components where feasible.
• Enhance detection with EDR rules targeting memory-corruption patterns and graphics subsystem calls.
• Validate backups and incident response playbooks to handle rapid escalation scenarios.
• If KEV true or EPSS ≥ 0.5, treat as priority 1. If not, maintain high-priority patching and monitoring.
