CVE-2025-20056 is a vulnerability identified in Intel VTune Profiler prior to version 2025.1. The root cause is improper input validation in the profiler's user-space components (Ring 3), which can be exploited by an unprivileged but authenticated local user. The flaw allows escalation of privilege through data manipulation, potentially altering the behavior or outputs of the profiler or related processes. The attack vector requires local access and low attack complexity, with no need for user interaction or special internal knowledge, making it relatively straightforward for an insider or compromised local account to exploit. The vulnerability primarily affects integrity and availability at a low level, meaning that while the system’s confidentiality remains intact, the attacker could cause limited data or process manipulation and potentially disrupt normal operations. The CVSS 4.8 rating reflects these factors, indicating a medium severity level. No public exploits have been reported, but the risk remains for environments where Intel VTune Profiler is deployed and accessible to lower-privileged users. Since VTune Profiler is a performance analysis tool used mainly by developers and engineers, the vulnerability could be leveraged to interfere with performance data or profiling results, potentially impacting development or operational diagnostics.

For European organizations, the impact of CVE-2025-20056 is primarily on the integrity and availability of systems running Intel VTune Profiler. While confidentiality is not affected, the ability of a low-privileged user to escalate privileges and manipulate data could undermine trust in performance analysis results, potentially leading to incorrect diagnostics or decisions based on corrupted profiling data. This could affect software development, testing, and optimization processes, especially in sectors relying heavily on performance tuning such as automotive, aerospace, and financial services. The low complexity and lack of required user interaction increase the risk in environments where local user accounts are shared or insufficiently controlled. Although the vulnerability does not directly compromise critical systems, the indirect effects on development and operational workflows could cause delays, misconfigurations, or degraded system performance. Given the lack of known exploits, the immediate threat is moderate, but organizations should not underestimate the potential for insider threats or lateral movement within networks.

European organizations should implement the following specific mitigations: 1) Upgrade Intel VTune Profiler to version 2025.1 or later as soon as patches become available to eliminate the vulnerability. 2) Restrict access to VTune Profiler installations to only trusted and necessary personnel, enforcing strict local user account management and minimizing the number of users with authenticated access. 3) Employ application whitelisting and endpoint protection solutions to monitor and control execution of profiling tools and related processes. 4) Conduct regular audits of user privileges and local account activities on systems running VTune Profiler to detect any anomalous behavior indicative of privilege escalation attempts. 5) Isolate development and profiling environments from critical production systems to limit the impact of any exploitation. 6) Educate developers and engineers about the risks of running outdated profiling tools and the importance of applying security updates promptly. These targeted actions go beyond generic advice by focusing on controlling local access, monitoring, and environment segmentation specific to the nature of this vulnerability.
