  "message": "KVM: MMU: Segregate shadow pages with different cr0.wp\n\nWhen cr0.wp\u003d0, we may shadow a gpte having u/s\u003d1 and r/w\u003d0 with an spte\nhaving u/s\u003d0 and r/w\u003d1.  This allows excessive access if the guest sets\ncr0.wp\u003d1 and accesses through this spte.\n\nFix by making cr0.wp part of the base role; we\u0027ll have different sptes for\nthe two cases and the problem disappears.\n\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\nSigned-off-by: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\n",
