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.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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.
    (CVE-2024-31143)

  - Certain PCI devices in a system might be assigned Reserved Memory Regions (specified via Reserved Memory
    Region Reporting, "RMRR") for Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used for
    platform tasks such as legacy USB emulation. Since the precise purpose of these regions is unknown, once a
    device associated with such a region is active, the mappings of these regions need to remain continuouly
    accessible by the device. In the logic establishing these mappings, error handling was flawed, resulting
    in such mappings to potentially remain in place when they should have been removed again. Respective
    guests would then gain access to memory regions which they aren't supposed to have access to.
    (CVE-2024-31145)

  - In x86's APIC (Advanced Programmable Interrupt Controller) architecture, error conditions are reported in
    a status register. Furthermore, the OS can opt to receive an interrupt when a new error occurs. It is
    possible to configure the error interrupt with an illegal vector, which generates an error when an error
    interrupt is raised. This case causes Xen to recurse through vlapic_error(). The recursion itself is
    bounded; errors accumulate in the the status register and only generate an interrupt when a new status bit
    becomes set. However, the lock protecting this state in Xen will try to be taken recursively, and
    deadlock. (CVE-2024-45817)

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

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

    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:
