CVE-2025-21093 is a vulnerability identified in Intel Driver & Support Assistant Tool software versions before 24.6.49.8. The issue arises from an uncontrolled search path element, which means the software improperly handles the directories it searches for executable files or libraries. This flaw can be exploited by an authenticated user with local access to escalate their privileges on the affected system. The vulnerability requires the attacker to have at least low-level privileges and to interact with the system locally, making remote exploitation infeasible. The CVSS 4.0 base score is 5.4, indicating medium severity, with attack vector limited to local access (AV:L), high attack complexity (AC:H), no authentication required (AT:N), low privileges required (PR:L), and user interaction needed (UI:P). The impact on confidentiality, integrity, and availability is high, meaning successful exploitation could allow significant unauthorized control or data compromise. Intel has reserved the CVE and published the advisory in August 2025, but no public exploits have been reported so far. The vulnerability affects Windows systems running the Intel Driver & Support Assistant Tool, which is widely used for managing Intel drivers and updates. The flaw could be leveraged by malicious insiders or malware that gains initial access with limited privileges to escalate to higher privileges, potentially compromising the entire system.

The primary impact of CVE-2025-21093 is the potential for privilege escalation on affected systems. An attacker with local access and low privileges could exploit this vulnerability to gain higher-level privileges, such as administrative or SYSTEM-level access. This escalation could enable unauthorized installation of software, modification of system configurations, or access to sensitive data. For organizations, this could lead to compromised endpoints, lateral movement within networks, and increased risk of data breaches or disruption of critical services. Since the Intel Driver & Support Assistant Tool is commonly installed on many enterprise and consumer Windows PCs, the scope of affected systems is broad. However, exploitation complexity and the requirement for local access limit the immediacy of risk from remote attackers. Still, insider threats or malware that achieves initial foothold could leverage this vulnerability to deepen system compromise. The lack of known exploits in the wild currently reduces immediate threat but does not eliminate future risk. Organizations relying on Intel hardware and software ecosystems should consider this vulnerability a significant risk to endpoint security and overall network integrity.

To mitigate CVE-2025-21093, organizations should promptly update the Intel Driver & Support Assistant Tool to version 24.6.49.8 or later, where the vulnerability is addressed. If immediate patching is not feasible, restrict local user permissions to the minimum necessary, preventing untrusted users from executing or modifying files in directories used by the Intel software. Implement application whitelisting to control which executables can run, reducing the risk of malicious code exploiting the search path flaw. Regularly audit and monitor local user activities for suspicious behavior indicative of privilege escalation attempts. Employ endpoint detection and response (EDR) solutions capable of detecting unusual privilege elevation patterns. Additionally, educate users about the risks of local privilege escalation and enforce strict physical and logical access controls to prevent unauthorized local access. Finally, maintain an up-to-date asset inventory to quickly identify systems running vulnerable versions of the Intel Driver & Support Assistant Tool for targeted remediation.
