CVE-2025-35998 Intel CVE debrief

Who should care

System administrators and security teams responsible for Intel-based systems should be aware of this vulnerability and take necessary steps to mitigate it. The vulnerability requires a privileged user account and special internal knowledge, but no user interaction. Therefore, it is essential to prioritize patching and ensure that all systems are up-to-date.

Technical summary

The vulnerability is caused by a missing protection mechanism for alternate hardware interfaces in the Intel Quick Assist Technology for some Intel Platforms within Ring 0: Kernel. This allows an adversary with a privileged user account and low complexity attack to enable escalation of privilege. The vulnerability has a CVSS score of 7 and affects the confidentiality (high) and integrity (high) of the vulnerable system. The vulnerability can be exploited via local access, and no user interaction is required.

Defensive priority

High priority should be given to patching this vulnerability, as it allows for privilege escalation and has a high CVSS score. System administrators and security teams should prioritize patching and ensure that all systems are up-to-date.

Recommended defensive actions

• Apply the patch provided by Intel to address the vulnerability.
• Ensure that all systems are up-to-date with the latest security patches.
• Implement additional security measures, such as access controls and monitoring, to detect and prevent exploitation.
• Conduct regular vulnerability assessments to identify and address potential vulnerabilities.
• Review and update incident response plans to ensure preparedness in case of an exploit.
• Consider implementing compensating controls, such as intrusion detection systems, to detect and prevent exploitation.
• Monitor system logs and network traffic for suspicious activity.
• Perform regular security audits to identify and address potential vulnerabilities.
