CVE-2021-28707
CVE-2021-28707 is a Xen hypervisor vulnerability affecting PoD (populate-on-demand) memory management for x86 HVM/PVH guests. The issue arises when handling PoD operations that act on page ranges (page orders); the base page frame number is not consistently enforced to be aligned for the requeste...
CVE-2021-28708
Xen PoD (populate-on-demand) handling contains a misalignment in base page frame number checks for certain hypercalls (XENMEM_decrease_reservation and XENMEM_populate_physmap). This affects x86 HVM/PVH guests and may allow out-of-bounds page-range operations; in particular, XENMEM_decrease_reserv...
