When multiple devices share resources and one of them is to be passed through to a guest, security of the entire system and of respective guests individually cannot really be guaranteed without knowing internals of any of the involved guests. Therefore such a configuration cannot really be security-supported, yet making that explicit was so far missing. Resources the sharing of which is known to be problematic include, but are not limited to - - PCI Base Address Registers (BARs) of multiple devices mapping to the same page (4k on x86), - - INTx lines.

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

    Multiple vulnerabilities have been discovered in the Xen hypervisor,     which could result in privilege escalation, denial of service or     information leaks.

    For the stable distribution (bookworm), these problems have been fixed in     version 4.17.5+23-ga4e5191dc0-1.

    We recommend that you upgrade your xen packages.

    For the detailed security status of xen please refer to     its security tracker page at:
