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 always be 4 levels deep. However, an IOMMU may require the use of just 3 page table levels. In such a configuration the lop level table needs to be stripped before inserting the root table's address into the hardware pagetable base register. When sharing page tables, Xen erroneously skipped this stripping. Consequently, the guest is able to write to leaf page table entries.

NVIDIA GPU and Tegra hardware contain a vulnerability in an internal microcontroller, which may allow a user with elevated privileges to generate valid microcode by identifying, exploiting, and loading vulnerable microcode. Such an attack could lead to information disclosure, data corruption, or denial of service of the device. The scope may extend to other components.

NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller, which may allow a user with elevated privileges to instantiate a DMA write operation only within a specific time window timed to corrupt code execution, which may impact confidentiality, integrity, or availability. The scope impact may extend to other components.
