Senserva AI Opinion for CVE-2026-32086
A second distinct elevation of privilege bug hits the Function Discovery Service's fdwsd.dll component, again Critical at 9.8 with the same 64 percent EPSS reading and the same Windows 11 26H1 and Windows 10 1809 footprint as the earlier fdwsd.dll fix in this batch. Function Discovery underlies device and printer discovery on a network, so it is commonly running by default on workstation builds. Neither KEV nor ransomware activity has been confirmed against this CVE.
Do this: Apply this fdwsd.dll fix alongside the other Function Discovery Service patch in this release; they are separate CVEs and both need the update installed.
