  "details": "In the Linux kernel, the following vulnerability has been resolved:  iommu/dma-iommu: Fix wrong scatterlist length assignment in P2PDMA path  In iommu_dma_map_sg(), when handling PCI P2PDMA cases, the DMA length of the current scatterlist segment `s` is incorrectly assigned from the head entry `sg-\u003elength` instead of the current entry `s-\u003elength`.  This typo causes all P2PDMA segments in the scatterlist to inherit the length of the first segment, leading to corrupted DMA lengths for multi- segment scatterlists.  Fix this by using `s-\u003elength` instead of `sg-\u003elength`.",
