The operating system may access memory without restriction (as opposed to user mode where memory
access is highly regulated by the OS… we hope). When the data is in memory the OS must be careful to
ensure that it is only accessing data that it needs to, since carelessness might result in overwriting data
pertaining to still-running user mode functions, breaking their operating when the OS shifts scope from
kernel mode back to user mode.
