CVE-2025-31647 is a vulnerability in Intel(R) Graphics Software prior to version 25.22.1502.2 that allows escalation of privilege due to an uncontrolled search path within Ring 3 user applications. The flaw enables an unprivileged, authenticated local attacker to exploit the software's search path handling to execute code or actions with elevated privileges. The vulnerability requires high attack complexity and active user interaction, such as convincing a user to run a malicious application or perform specific actions. The uncontrolled search path means the software may load malicious components or libraries placed by the attacker in locations searched before legitimate ones, leading to privilege escalation. The CVSS 4.0 score is 5.4 (medium), reflecting local attack vector, high complexity, partial privileges required, and user interaction. The vulnerability impacts confidentiality, integrity, and availability at a high level, potentially allowing attackers to compromise system security fully. No public exploits are known, but the risk remains for targeted attacks. The vulnerability affects Intel Graphics Software widely deployed in desktops and laptops, making it relevant to many organizations. The issue is mitigated by updating to version 25.22.1502.2 or later, which presumably corrects the search path handling. Additional mitigations include restricting local user permissions and monitoring for suspicious local activity.

For European organizations, this vulnerability poses a significant risk primarily in environments where Intel Graphics Software is widely used, including corporate desktops, workstations, and possibly servers with integrated graphics. Successful exploitation could allow attackers to gain elevated privileges from a low-privilege user account, potentially enabling lateral movement, installation of persistent malware, or access to sensitive data. The high impact on confidentiality, integrity, and availability means critical systems could be compromised, leading to data breaches, operational disruptions, or loss of trust. Sectors such as finance, government, healthcare, and critical infrastructure in Europe could be particularly affected due to their reliance on secure computing environments and the prevalence of Intel hardware. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk in environments with many users or shared systems. The absence of known exploits reduces immediate threat but does not preclude targeted attacks or future exploit development.

1. Immediately update Intel Graphics Software to version 25.22.1502.2 or later to apply the official fix addressing the uncontrolled search path vulnerability. 2. Implement strict local user account controls to limit the ability of unprivileged users to place or execute unauthorized code in directories searched by the graphics software. 3. Employ application whitelisting and endpoint protection solutions to detect and block suspicious local activities or unauthorized code execution attempts. 4. Educate users about the risks of running untrusted applications and the importance of avoiding suspicious interactions that could trigger the vulnerability. 5. Regularly audit and monitor local system environments for signs of privilege escalation attempts or anomalous behavior related to graphics software processes. 6. Restrict physical and remote access to sensitive systems to reduce opportunities for local exploitation. 7. Coordinate with Intel and security vendors for any additional patches or advisories related to this vulnerability.
