    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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-987548 advisory.

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