CVE-2026-53164

The CVE-2026-53164 entry concerns the Linux kernel IOMMU DMA SWIOTLB path. The vulnerability arises when iommu_dma_iova_link_swiotlb() maps an unaligned memory region and, if the middle portion is empty, calls iommu_map() with a 0 size, which the iommu_pt implementation treats as illegal, corrupt...
