Summary
In the Linux kernel, the following vulnerability has been resolved: net: arc: fix the device for dma_map_single/dma_unmap_single The ndev->dev and pdev->dev aren't the same device, use ndev->dev.parent which has dma_mask, ndev->dev.parent is just pdev->dev. Or it would cause the following issue: [ 39.933526] ------------[ cut here ]------------ [ 39.938414] WARNING: CPU: 1 PID: 501 at kernel/dma/mapping.c:149 dma_map_page_attrs+0x90/0x1f8
