Senserva AI Opinion for CVE-2026-32093

Function Discovery Service (fdwsd.dll) carries a Critical elevation of privilege flaw with a 9.8 CVSS score, and Microsoft's own EPSS model puts the odds of exploitation at 64 percent, an unusually high figure for a flaw not yet in the CISA KEV catalog. It reaches across the current 26H1 build of Windows 11 as well as the long-lived Windows 10 1809 branch, so both freshly upgraded and legacy fleets carry the exposure. No ransomware group has adopted it yet, but a 64 percent EPSS score means that could change quickly.

Do this: Patch Windows 11 26H1 and any remaining Windows 10 1809 systems for this update in the next cycle rather than waiting for the next scheduled maintenance window.
