Analysis

Impact

This vulnerability is an uncontrolled search path element in the Windows AI subsystem that allows an attacker who already has local access to elevate privileges. The flaw, classified as CWE-427, means an application can unknowingly load code from an unexpected directory, giving the attacker command execution capabilities with higher privileges.

Affected Systems

Affected are Windows 11 24H2, 25H2, 26H2, 26H1 and Windows Server 2025, including the Server Core installation. These versions run on ARM64‑based systems and expose the AI component that handles uncategorized search paths.

Risk and Exploitability

The CVSS score of 7.8 indicates a high severity risk. No EPSS data is available, so the current exploit probability is unknown. The vulnerability is not listed in the CISA KEV catalog, but the attack vector would be local, requiring an authenticated user with sufficient permissions to trigger the AI subsystem. The likelihood of exploitation is therefore tied to the presence of privileged users on the target machine.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
