Name of the Vulnerable Software and Affected Versions
AMD-Vi (affected versions not specified)
Description
The caching invalidation guidelines from the AMD-Vi specification are incorrect on some hardware, leading to devices malfunctioning if some fields of the DTE are updated but the IOMMU TLB is not flushed. This can cause stale DMA mappings, allowing access to unintended memory regions not owned by the guest.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
