"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-001102 advisory.

    Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command
    registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and
    host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing
    the device, which triggers an Unsupported Request (UR) response.

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.");
