In the Linux kernel, the following vulnerability has been resolved:
bnxten: Fix double DMA unmapping for XDPREDIRECT
Remove the dmaunmappageattrs() call in the driver's XDPREDIRECT code path. This should have been removed when we let the page pool handle the DMA mapping. This bug causes the warning:
