Description Brent Fulgham 2021-05-04 16:05:17 PDT
Deny access to 'nvram' in the WebKit sandboxes. No API surface interacts with this low-level feature, and other system sandboxes already deny it. It should not have been possible to reach nvram, but there's no reason to allow the sandbox to access it.

Confirmed proper function on iOS device and macOS. Waiting for EWS to show any other impact on downlevel platforms.
