CVE-2024-25939

What it actually does

Mirrored regions with different values in 3rd Generation Intel Xeon Scalable Processors allow a privileged local user to trigger denial of service.

Why it matters to the business

Potential server downtime and operational disruption on systems using affected processors, increasing risk for organizations reliant on stable infrastructure despite low exploit likelihood.

How an attack unfolds

A privileged local attacker identifies and manipulates inconsistent mirrored memory regions on the processor to induce a denial of service condition.

How to fix it

Apply hardware microcode updates for affected Intel processors; for listed software environments update drupal (Bitnami) to version 9.3.19 or later.

How to confirm the fix worked

Confirm microcode versions on Intel processors and verify system stability after updates; test affected hardware configurations for the described memory mirroring behavior.

Typical attack path

1. Obtain local privileged access to the target system
2. Interact with processor memory mirroring mechanisms
3. Introduce differing values into mirrored regions
4. Trigger hardware-level denial of service

How to detect it

Review system event logs for processor errors related to memory mirroring or hardware faults on affected Intel Xeon platforms.

What your security team should do

• Prioritize microcode and firmware updates on all systems with 3rd Generation Intel Xeon Scalable Processors
• Restrict unnecessary local privileged access
• Monitor system logs for hardware error events indicating memory inconsistencies
