Name of the Vulnerable Software and Affected Versions macOS versions prior to 10.13.1

Description The issue involves the "Kernel" component and allows attackers to bypass intended memory-read restrictions. This is achieved via a /dev/dtracehelper attack that involves the dtrace dif variable and dtrace getarg functions.

Recommendations For macOS versions prior to 10.13.1, update to version 10.13.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the /dev/dtracehelper endpoint to minimize the risk of exploitation.
