  "description": "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 \u0060s\u0060 is incorrectly assigned from the head entry \u0060sg-\u003Elength\u0060 instead of the current entry \u0060s-\u003Elength\u0060.  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 \u0060s-\u003Elength\u0060 instead of \u0060sg-\u003Elength\u0060.",
