  that is continuously integrity checked as programs are loaded into RAM for execution. This means
  that if a device is somehow compromised, a reboot should clear the issue from the device.

  This vulnerability allows an attacker that has already compromised the device, and therefore has
  the ability to modify internal configuration files, to make their compromise persistent, meaning
  after a device is rebooted, it will remain compromised.

  NOTE: This vulnerability cannot be used to compromise a device, it can only be used on a device
  that has already been compromised by another means.");
