Risk summary
Listed in the CISA Known Exploited Vulnerabilities catalog, confirmed exploited in the wild. EPSS exploit probability 61%. CVSS 7.8 (High).
This CVE is among the top half of tracked Microsoft CVEs by EPSS exploit probability, and one of 4 actively-exploited CVEs in May 2025.
This is a Common Log File System driver flaw that lets a local attacker escalate to SYSTEM privileges, and CISA confirmed active exploitation on 2025-05-13. Windows 10 version 1809 and Windows Server 2019 are the exposed systems, and with a 58 percent EPSS score and confirmed in-the-wild use, this is a realistic post-compromise escalation path rather than a theoretical one. CLFS driver bugs like this are a recurring target because they run in kernel context and are present on default installs.
Do this: Deploy the Microsoft May 2025 patch for CVE-2025-32706 to all Windows 10 1809 and Server 2019 hosts now, prioritizing internet-facing and multi-user machines.
