CVE-2025-20023 is a vulnerability identified in Intel Graphics Driver software installers where incorrect default permissions are set. These improper permissions can be exploited by an authenticated user with limited privileges to escalate their privileges on the local machine. The vulnerability arises because the installer software grants more access rights than necessary, allowing a user to manipulate the installer or related files to gain elevated privileges. The CVSS 4.0 score is 5.4, indicating a medium severity level, with an attack vector limited to local access (AV:L), high attack complexity (AC:H), and requiring partial privileges (PR:L) and user interaction (UI:A). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H), meaning successful exploitation could compromise system security significantly. No known exploits have been reported in the wild, and no patches are explicitly linked yet, though Intel is the assigner and likely to release updates. This vulnerability affects versions of Intel Graphics Driver installers as referenced by Intel, typically found on many Windows-based systems using Intel integrated graphics hardware. The flaw does not require network access but does require an authenticated user, limiting remote exploitation but posing a risk in environments where multiple users share systems or where attackers gain initial access with low privileges.

The primary impact of CVE-2025-20023 is the potential for local privilege escalation, allowing an attacker with limited user rights to gain higher privileges, potentially administrative or SYSTEM level. This can lead to unauthorized access to sensitive data, modification or deletion of critical system files, installation of persistent malware, and disruption of system operations. In enterprise environments, this could facilitate lateral movement within networks, undermining endpoint security and increasing the risk of broader compromise. Since Intel Graphics Drivers are widely deployed on personal computers, workstations, and some servers globally, the vulnerability poses a significant risk to organizations relying on Intel hardware. The requirement for local access and user interaction reduces the likelihood of remote exploitation but does not eliminate the threat in multi-user or compromised environments. The absence of known exploits in the wild currently lowers immediate risk but does not preclude future exploitation once details become public or patches are delayed.

Organizations should immediately audit the permissions of Intel Graphics Driver software installers on their systems to ensure they are not overly permissive. Restrict installer file and directory permissions to trusted administrators only, preventing unauthorized modification. Monitor local user activities for suspicious behavior indicative of privilege escalation attempts. Apply the latest Intel driver updates and security patches as soon as they become available, following Intel’s advisories closely. Employ endpoint protection solutions capable of detecting privilege escalation techniques and enforce least privilege principles for user accounts. In environments with shared or multi-user systems, consider additional controls such as application whitelisting and enhanced user session monitoring. Conduct regular security training to raise awareness about the risks of local privilege escalation and the importance of not executing untrusted installers or software.
