Local privilege escalation via weak auth in Windows WMI
Weak authentication in Windows Management Instrumentation lets an already authorized user raise privileges on the same machine.

Microsoft has not listed affected builds or a fixed version.
What to do: Apply Microsoft's update for CVE-2026-105524 when it is available. No workaround is stated.
