    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.

  - An optional feature of PCI MSI called Multiple Message allows a device to use multiple consecutive     interrupt vectors. Unlike for MSI-X, the setting up of these consecutive vectors needs to happen all in     one go. In this handling an error path could be taken in different situations, with or without a     particular lock held. This error path wrongly releases the lock even when it is not currently held.

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