Does this matter?
Lower severity and a low EPSS score (1.59%). Track it; it rarely justifies an emergency change on its own.

The issue was addressed with improved permissions logic. This issue is fixed in macOS Monterey 12.0.1, macOS Big Sur 11.6.1. An unprivileged application may be able to edit NVRAM variables.
