Senserva AI Opinion for CVE-2024-43554

A kernel-mode driver disclosure shares the same elevated 61 percent EPSS and Critical 9.0 rating as the graphics component bug above, but on the older Windows 10 Version 1809 and Windows Server 2019 rather than Windows 11. Seeing this same high exploitation forecast on both a legacy and a current platform in this release suggests attackers are actively developing techniques against kernel-mode drivers across OS generations.

Do this: Patch 1809 and Server 2019 systems for this driver fix with the same urgency as the Windows 11 graphics fix in this release.
