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

  - PCI/bwctrl: Fix NULL pointer dereference on bus number exhaustion When BIOS neglects to assign bus numbers     to PCI bridges, the kernel attempts to correct that during PCI device enumeration. If it runs out of bus     numbers, no pci_bus is allocated and the subordinate pointer in the bridge's pci_dev remains NULL. The     PCIe bandwidth controller erroneously does not check for a NULL subordinate pointer and dereferences it on     probe. Bandwidth control of unusable devices below the bridge is of questionable utility, so simply error     out instead. This mirrors what PCIe hotplug does since commit 62e4492c3063 (PCI: Prevent NULL dereference     during pciehp probe). The PCI core emits a message with KERN_INFO severity if it has run out of bus     numbers. PCIe hotplug emits an additional message with KERN_ERR severity to inform the user that hotplug     functionality is disabled at the bridge. A similar message for bandwidth control does not seem merited,     given that its only purpose so far is to expose an up-to-date link speed in sysfs and throttle the link     speed on certain laptops with limited Thermal Design Power. So error out silently. User-visible messages:
    pci 0000:16:02.0: bridge configuration invalid ([bus 00-00]), reconfiguring [...] pci_bus 0000:45:

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