[PATCH 0/1] Fix protection fault during kernel relocation

Posted by Christian Bruel 1 month, 2 weeks ago

A trusted boot firmware might set the CTLR.WWN bits, preventing execution
of the relocated code treated as XN permission.
Another solution to clear the CTLR.WXN and CTLR.UWXN bits but would open a
security breach.

Best is probably just not to use the Client access domain here.

thanks,
