CVE-2021-28710

certain VT-d IOMMUs may not work in shared page table mode For efficiency reasons, address translation control structures page tables may and, on suitable hardware, by default will be shared between CPUs, for second-level translation EPT, and IOMMUs. These page tables are presently set up to alwa...

CVE-2021-28710

CVE-2021-28710 affects the Xen hypervisor on x86 VT-d IOMMUs when sharing page tables. The bug arises because the top-level strip of the 3-level page tables was skipped while inserting the root page-table address into the hardware pagetable base register, allowing a guest to write to leaf page-ta...
