Certain MMU virtualization operations in Xen 4.2.x through 4.4.x before the xsa97-hap patch, when using Hardware Assisted Paging (HAP), are not preemptible, which allows local HVM guest to cause a denial of service (vcpu consumption) by invoking these operations, which process every page assigned to a guest, a different vulnerability than CVE-2014-5149.

Security readout for executives and security teams

This issue affects Xen hypervisors in specific older versions. A guest virtual machine can force the host to spend excessive CPU time on certain memory-management work, potentially degrading or denying service to other workloads on the same host. Exposure is most likely in environments still running affected Xen 4.2.x to 4.4.x builds, using HAP, and hosting HVM guests. Risk is higher where guests are untrusted or multi-tenant. Treat as moderate priority unless affected Xen hosts run untrusted guest workloads. For multi-tenant virtualization, schedule prompt remediation because one guest can affect shared host availability. Mitigation focus: Apply the Xen XSA-97 HAP patch or fixed vendor package.; Review Gentoo, Fedora, and openSUSE advisories if using their Xen packages.; Prioritize hosts running untrusted or multi-tenant HVM guests..
