NVD Description
Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Alpine.
See How to fix? for Alpine:3.20 relevant fixed versions and status.
The caching invalidation guidelines from the AMD-Vi specification (48882—Rev 3.07-PUB—Oct 2022) is incorrect on some hardware, as devices will malfunction (see stale DMA mappings) if some fields of the DTE are updated but the IOMMU TLB is not flushed.
Such stale DMA mappings can point to memory ranges not owned by the guest, thus allowing access to unindented memory regions.
