    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.

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

  - Unlike 32-bit PV guests, HVM guests may switch freely between 64-bit and other modes. This in particular     means that they may set registers used to pass 32-bit-mode hypercall arguments to values outside of the     range 32-bit code would be able to set them to. When processing of hypercalls takes a considerable amount     of time, the hypervisor may choose to invoke a hypercall continuation. Doing so involves putting (perhaps     updated) hypercall arguments in respective registers. For guests not running in 64-bit mode this further     involves a certain amount of translation of the values. Unfortunately internal sanity checking of these     translated values assumes high halves of registers to always be clear when invoking a hypercall. When this     is found not to be the case, it triggers a consistency check in the hypervisor and causes a crash.
    (CVE-2023-46842)

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