  "description": "In the Linux kernel, the following vulnerability has been resolved:  iommu/amd: Fix potential out-of-bounds read in iommu_mmio_show  In iommu_mmio_write(), it validates the user-provided offset with the check: \u0060iommu-\u003Edbg_mmio_offset \u003E iommu-\u003Emmio_phys_end - 4\u0060. This assumes a 4-byte access. However, the corresponding show handler, iommu_mmio_show(), uses readq() to perform an 8-byte (64-bit) read.  If a user provides an offset equal to \u0060mmio_phys_end - 4\u0060, the check passes, and will lead to a 4-byte out-of-bounds read.  Fix this by adjusting the boundary check to use sizeof(u64), which corresponds to the size of the readq() operation.",
