Senserva AI Opinion for CVE-2025-48004

CVE-2025-48004 is a Brokering File System elevation-of-privilege vulnerability with an exceptionally high Critical 9.9 CVSS but only a 6 percent EPSS score, and it targets the latest Windows 11 25H2 and 22H2 on x64 and ARM64. The severity reflects a near-total impact if exploited, while the low EPSS suggests it is not yet a probable target. No confirmed exploitation or ransomware use exists.

Do this: Patch Windows 11 25H2 and 22H2 endpoints, including ARM64, and prioritize by the 9.9 impact rating even though current exploit likelihood is low.
