CVE-2022-23035

CVE-2022-23035 affects the Xen hypervisor with PCI passthrough to x86 HVM guests. The issue is insufficient cleanup of IRQs for passed-through devices: if an interrupt isn’t quiescent during cleanup, a retry may be skipped and pointers can be cleared/freed, risking de-reference of NULL and a use-...

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...

CVE-2021-28705

CVE-2021-28705 and CVE-2021-28709 concerns Xen hypervisor on x86 HVM/PVH guests running in populate-on-demand (PoD). The issue stems from partial success handling of P2M updates in hypercalls that operate on page ranges; requests may be split into chunks leading to insufficient accounting of part...
