Risk summary

Senserva AI Opinion for CVE-2025-62458

Win32k, the graphics subsystem driver with a long track record of weaponized privilege escalations, is the component at fault here on Windows 10 1809 and Windows Server 2019. Rated High Severity at CVSS 8.8, it lets local code jump from user to elevated rights. EPSS is low at 2 percent and there is no KEV entry, but Win32k bugs have a habit of getting exploited after patch release.
