The bug is     caused by overrunning the sglist and incorrectly testing sg_dma_len(sglist) before nents. Normally this     doesn't cause a crash, but in this case sglist crossed a page boundary. This occurs in the following code:
    while (sg_dma_len(sglist) && nents--) { The fix is simply to test nents first and move the decrement of     nents into the loop. (CVE-2022-48795)
