grant table v2 status pages may remain accessible after de-allocation
ISSUE DESCRIPTION Guest get permitted access to certain Xen-owned pages of memory. The majority of such pages remain allocated / associated with a guest for its entire lifetime. Grant table v2 status pages, however, get de-allocated when a guest switched back from v2 to v1. The freeing of such...
CVE-2021-28691
