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

  - powerpc/pseries: Fix use after free in remove_phb_dynamic() In remove_phb_dynamic() we use     &phb->io_resource, after we've called device_unregister(&host_bridge->dev). But the unregister may have     freed phb, because pcibios_free_controller_deferred() is the release function for the host_bridge. If     there are no outstanding references when we call device_unregister() then phb will be freed out from under     us. This has gone mainly unnoticed, but with slub_debug and page_poison enabled it can lead to a crash:

Then when we drop the reference     the phb will be freed. (CVE-2022-49196)
