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 `s` is incorrectly assigned from the head entry `sg->length` instead of the current entry `s->length`. 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->length` instead of `sg->length`.
