kernel: iommu/vt-d: Disallow dirty tracking if incoherent page walk

A flaw was found in the Intel VT-d IOMMU support in the Linux kernel. When an IOMMU is configured to perform dirty-page tracking, but the page-walk memory region is incoherent between the IOMMU and CPU, the hardware may attempt to atomically update the bits in a paging-structure entry that is not...

CVE-2023-53801

In the Linux kernel, the following vulnerability has been resolved: iommu/sprd: Release dma buffer to avoid memory leak When attaching to a domain, the driver would alloc a DMA buffer which is used to store address mapping table, and it need to be released when the IOMMU domain is freed...

CVE-2023-53789 iommu/amd: Improve page fault error reporting

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Improve page fault error reporting If IOMMU domain for device group is not setup properly then we may hit IOMMU page fault. Current page fault handler assumes that domain is always setup and it will hit NULL pointer...
