CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2026-20772 impacting intel connectivity_performance_suite. Evaluated with CVSS Base Score of 6.7 (MEDIUM).

Original NVD Description

Source: NIST NVD
Uncontrolled search path for some Intel(R) Connectivity Performance Suite software installers before version 50.25.1121.193 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
