CVE-2025-32453 is a vulnerability identified in Intel Graphics Driver software that arises from incorrect default permissions assigned to components operating within Ring 2, a privileged process level in the CPU architecture. This misconfiguration allows an unprivileged adversary, who is an authenticated local user, to escalate their privileges on the affected system. The attack complexity is high, meaning exploitation requires significant effort and expertise, and active user interaction is necessary, which limits remote or automated exploitation scenarios. The vulnerability impacts confidentiality, integrity, and availability of the system at a high level if successfully exploited. However, the vulnerability does not lead to further system-wide impacts beyond the compromised process. The CVSS 4.0 vector indicates that the attack requires local access (AV:L), high attack complexity (AC:H), privileges of a low-level user (PR:L), and user interaction (UI:A). The vulnerability does not involve scope change or special privileges beyond the local user context. No known exploits have been reported in the wild, and no patches or detailed affected versions have been publicly disclosed yet. The vulnerability was reserved in April 2025 and published in February 2026, indicating recent discovery and disclosure. Intel Graphics Drivers are widely used in various computing environments, including desktops and laptops, making this vulnerability relevant for many organizations relying on Intel hardware.

For European organizations, this vulnerability poses a risk primarily to systems utilizing Intel Graphics Drivers, which are common in enterprise desktops, workstations, and laptops. Successful exploitation could allow a local attacker to gain elevated privileges, potentially enabling unauthorized access to sensitive data, modification of system configurations, or disruption of system availability. This is particularly concerning for sectors handling sensitive information such as finance, healthcare, and government institutions. The requirement for local access and user interaction limits the attack vector to insider threats or scenarios where an attacker has already compromised a user account. However, the high impact on confidentiality, integrity, and availability means that if exploited, the consequences could be severe, including data breaches or system downtime. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time. Organizations with remote work policies should also consider the risk of compromised endpoints being exploited locally by malicious users or malware. Overall, the vulnerability could undermine trust in endpoint security and complicate compliance with data protection regulations such as GDPR if exploited.

Organizations should prioritize monitoring for updates and patches from Intel addressing this vulnerability and apply them promptly once available. Until patches are released, restricting local user permissions and limiting the number of users with authenticated access to systems running Intel Graphics Drivers can reduce risk. Employing endpoint detection and response (EDR) solutions to monitor for unusual privilege escalation attempts or suspicious user activity is recommended. User education to prevent social engineering or inadvertent activation of malicious payloads is important given the requirement for active user interaction. Implementing strict application whitelisting and least privilege principles can further mitigate exploitation chances. Regularly auditing system permissions and configurations related to graphics driver components may help identify and remediate misconfigurations. For organizations with remote or hybrid workforces, ensuring secure remote access and endpoint security hygiene is critical to prevent local exploitation by attackers who gain initial footholds. Finally, maintaining comprehensive incident response plans to quickly address any detected exploitation attempts will minimize potential damage.
