    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.

    - CVE-2024-45817: Fixed a deadlock in vlapic_error (XSA-462, bsc#1230366)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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

  - 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)

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