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

  - In the Linux kernel, the following vulnerability has been resolved: ocxl: fix pci device refcount leak     when calling get_function_0() get_function_0() calls pci_get_domain_bus_and_slot(), as comment says, it     returns a pci device with refcount increment, so after using it, pci_dev_put() needs be called. Get the     device reference when get_function_0() is not called, so pci_dev_put() can be called in the error path and     callers unconditionally. And add comment above get_dvsec_vendor0() to tell callers to call pci_dev_put().
    (CVE-2022-50337)

Note that Nessus relies on the presence of the package as reported by the vendor.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993310 advisory.

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

    ocxl: fix pci device refcount leak when calling get_function_0()

    get_function_0() calls pci_get_domain_bus_and_slot(), as comment     says, it returns a pci device with refcount increment, so after     using it, pci_dev_put() needs be called.

    Get the device reference when get_function_0() is not called, so     pci_dev_put() can be called in the error path and callers     unconditionally. And add comment above get_dvsec_vendor0() to tell     callers to call pci_dev_put().

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.
