Setting list for settings.kernel

Full Reference

settings.kernel.lockdown

Sets the mode for the lockdown Linux security module.

Default: integrity except for nvidia and dev variant flavours which use none

Accepted values:
  • confidentiality : blocks most methods of reading kernel memory from userspace. Tools that rely on reading kernel memory may not work in this mode.
  • integrity : blocks most methods for overwriting kernel memory or modifying kernel code. This mode prevents unsigned kernel modules from loading.
  • none : disables protection by the Lockdown security module.
