CVE-2025-32706: Windows Common Log File System Driver Elevation of Privilege Vulnerability

Noroxi assessment

Priority: This week (action score 62/100)

  • CISA has confirmed exploitation in the wild (May 13, 2025). Remediation deadline for US federal agencies: Jun 3, 2025.
  • Probability of exploitation in the next 30 days: 2.3% (FIRST EPSS); higher than 83.4% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Windows 10 for 32-bit Systems 10.0.10240.21014; Windows 10 for x64-based Systems 10.0.10240.21014; Windows 10 Version 1607 for 32-bit Systems 10.0.14393.8066.

Don’t wait for the next maintenance window. Upgrade to Windows 10 for 32-bit Systems 10.0.10240.21014; Windows 10 for x64-based Systems 10.0.10240.21014; Windows 10 Version 1607 for 32-bit Systems 10.0.14393.8066 or later.
