The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-131772 advisory.

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

    scsi: mpt3sas: Limit NVMe request size to 2 MiB

    The HBA firmware reports NVMe MDTS values based on the underlying drive     capability. However, because the driver allocates a fixed 4K buffer for     the PRP list, accommodating at most 512 entries, the driver supports a     maximum I/O transfer size of 2 MiB.

    Limit max_hw_sectors to the smaller of the reported MDTS and the 2 MiB     driver limit to prevent issuing oversized I/O that may lead to a kernel     oops.

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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
