Details

In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Fix double DMA unmapping for XDP_REDIRECT

Remove the dma_unmap_page_attrs() call in the driver's XDP_REDIRECT code path. This should have been removed when we let the page pool handle the DMA mapping. This bug causes the warning:
