CVE-2025-20047: Escalation of Privilege in Intel(R) Core™ Ultra Processors
Improper locking in the Intel(R) Integrated Connectivity I/O interface (CNVi) for some Intel(R) Core™ Ultra Processors may allow an unauthenticated user to potentially enable escalation of privilege via physical access.
AI Analysis
Technical Summary
CVE-2025-20047 is a medium-severity vulnerability affecting Intel(R) Core™ Ultra Processors, specifically related to improper locking mechanisms within the Intel Integrated Connectivity I/O interface (CNVi). This flaw allows an unauthenticated attacker with physical access to the affected hardware to potentially escalate privileges. The vulnerability arises because the CNVi interface does not properly enforce locking, which could enable an attacker to bypass normal privilege boundaries and execute code or commands with elevated privileges. The vulnerability does not require user interaction or prior authentication but does require physical access to the device, which limits the attack vector primarily to scenarios where an attacker can directly interact with the hardware. The CVSS 4.0 base score is 5.3, reflecting a medium severity level, with attack vector classified as physical (AV:P), high attack complexity (AC:H), and no privileges required (PR:N). The impact on confidentiality and integrity is high, while availability and authentication are not affected. No known exploits are currently reported in the wild, and no patches or mitigations have been explicitly linked in the provided data. This vulnerability is significant because Intel Core Ultra processors are widely used in modern computing devices, including laptops and desktops, which are common in enterprise environments. The improper locking in CNVi could be exploited to gain unauthorized control over the system, potentially leading to data breaches or further compromise of the device.
Potential Impact
For European organizations, this vulnerability poses a risk primarily in environments where physical security controls are insufficient, such as shared workspaces, public access areas, or during device transport and maintenance. An attacker with physical access could exploit this flaw to escalate privileges and gain unauthorized control over systems running Intel Core Ultra processors. This could lead to unauthorized data access, installation of persistent malware, or disruption of critical business operations. Sectors with high-value intellectual property, sensitive personal data, or critical infrastructure components could be particularly impacted. The medium severity rating suggests the risk is moderate but should not be ignored, especially in organizations with less stringent physical security or where devices are frequently handled by multiple personnel. Additionally, the lack of known exploits in the wild currently reduces immediate risk, but the presence of a publicly known vulnerability increases the likelihood of future exploitation attempts. European organizations must consider this vulnerability in their risk assessments, particularly those in finance, healthcare, government, and technology sectors, where the confidentiality and integrity of data are paramount.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should implement strict physical security controls to prevent unauthorized access to devices equipped with Intel Core Ultra processors. This includes secure storage, controlled access to hardware, and monitoring of device handling. Organizations should also ensure that all firmware and system software are kept up to date with the latest security patches from Intel and device manufacturers as they become available. While no specific patches are referenced in the provided data, monitoring Intel advisories and applying updates promptly is critical. Additionally, organizations should consider deploying endpoint detection and response (EDR) solutions capable of detecting unusual privilege escalation attempts or hardware tampering. For high-security environments, employing hardware-based security modules or trusted platform modules (TPMs) can provide additional layers of protection. Finally, educating staff about the risks of physical device access and enforcing policies around device handling and maintenance can reduce the attack surface related to this vulnerability.
