* | KVM: MMU: Segregate shadow pages with different cr0.wp | Avi Kivity | 2010-05-19 |
| | | | | | | | | | | | | When cr0.wp=0, we may shadow a gpte having u/s=1 and r/w=0 with an spte having u/s=0 and r/w=1. This allows excessive access if the guest sets cr0.wp=1 and accesses through this spte. Fix by making cr0.wp part of the base role; we'll have different sptes for the two cases and the problem disappears.
