Design/Logic Flaw

Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes such as the ones during scrubbing have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the...

UBUNTU-CVE-2023-34326

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 range...
