Senserva AI Opinion for CVE-2016-0165

A decade old this year, this Win32k privilege escalation still earns its KEV listing (2023-06-22) because kernel escalation bugs remain useful long after disclosure: any code running as a user can leverage it toward SYSTEM. Severity is High. The machines at risk are the unpatched Windows holdouts, which are precisely the machines attackers can still find.

Do this: Sweep for Windows hosts missing 2016-era kernel updates and patch or retire them.
