Senserva AI Opinion for CVE-2025-62454

The Cloud Files mini filter driver is the kernel component behind OneDrive files-on-demand, so this High Severity (CVSS 8.8) elevation of privilege flaw is present on virtually every OneDrive-enabled endpoint running Windows 11 25H2 or Windows 10 1809. Malware that lands as a standard user can use it to take full control of the machine. EPSS estimates a 5 percent exploitation probability, modest but not negligible for a driver class attackers know well.

Do this: Push the current cumulative update to OneDrive-heavy Windows 11 25H2 and Windows 10 1809 fleets first.
