Senserva AI Opinion for CVE-2024-38246

Win32k again appears with an elevation of privilege bug, this time on Server 2022 and the older Windows 11 21H2, rated Critical with a 71 percent EPSS. Given Win32k's history as one of the most commonly weaponized privilege escalation surfaces, a 71 percent exploitation likelihood should be read as a strong signal to prioritize.

Do this: Patch Server 2022 and Windows 11 21H2 systems for this Win32k fix ahead of lower-EPSS items in the same release.
