Risk summary
Not in the CISA KEV catalog. EPSS exploit probability 71%. CVSS 7.8 (High).
This CVE is among the top 25% of tracked Microsoft CVEs by EPSS exploit probability.
This is a Common Log File System (CLFS) driver privilege escalation flaw, the same driver family attackers repeatedly abuse to jump from a local foothold to SYSTEM. It hits Windows 11 24H2 on both ARM64 and x64 plus Windows 10 1809 32-bit, and the 71 percent EPSS score signals that working exploit code is likely near. It is not yet in CISA KEV or tied to ransomware, but CLFS bugs have a strong track record of being weaponized fast.
Do this: Deploy the current Microsoft cumulative update to all Windows 11 24H2 and Windows 10 1809 endpoints now, prioritizing multi-user and internet-facing machines.
