CVE-2025-26404 is a vulnerability identified in Intel(R) Dynamic System Analysis (DSA) software versions before 25.2.15.9. The issue stems from an uncontrolled search path, which means the software improperly handles the locations from which it loads certain resources or executables. This flaw can be exploited by an authenticated user with local access to the system, potentially allowing them to escalate their privileges beyond their assigned level. The vulnerability requires the attacker to have at least low-level privileges and to perform some user interaction, making exploitation more complex. The CVSS 4.0 score of 5.4 reflects a medium severity, considering the high attack complexity and required privileges, but also the significant impact on confidentiality, integrity, and availability if exploited. The vulnerability does not require network access and is limited to local exploitation, which reduces the attack surface but still poses a serious risk in environments where multiple users have local access. Intel has published this vulnerability in March 2025, and it is currently in a published state with no known active exploits in the wild. The root cause is related to the software's search path handling, which could allow an attacker to substitute or influence the loading of malicious components, thereby gaining elevated privileges.

If exploited, this vulnerability could allow an authenticated local user to gain higher privileges on the affected system, potentially leading to unauthorized access to sensitive data, modification or deletion of critical files, and disruption of system operations. This escalation of privilege could undermine the security controls in place, allowing attackers to bypass restrictions and execute arbitrary code with elevated rights. In enterprise environments, this could lead to lateral movement within networks, data breaches, or disruption of critical services. The impact spans confidentiality, integrity, and availability, as attackers could access confidential information, alter system configurations, or cause denial of service. Although exploitation requires local access and user interaction, environments with multiple users or shared access are particularly vulnerable. The absence of known exploits in the wild currently limits immediate risk, but the presence of the vulnerability necessitates prompt remediation to prevent future attacks.

Organizations should prioritize updating Intel DSA software to version 25.2.15.9 or later, where this vulnerability is addressed. In addition to patching, restrict local access to systems running Intel DSA to trusted users only, employing strict access controls and user account management. Implement application whitelisting and integrity monitoring to detect unauthorized changes to software components or execution paths. Employ endpoint detection and response (EDR) solutions to monitor for suspicious privilege escalation attempts. Conduct regular audits of user privileges and system logs to identify anomalous activities. Where possible, isolate critical systems running Intel DSA from general user environments to reduce exposure. Educate users about the risks of executing untrusted code or interacting with suspicious prompts that could facilitate exploitation. Finally, maintain an up-to-date inventory of affected systems to ensure comprehensive remediation.
