Certain MMU virtualization operations in Xen 4.2.x through 4.4.x, when using shadow pagetables, 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-2014-5146.

Security readout for executives and security teams

CVE-2014-5149 is a Xen hypervisor denial-of-service issue. In Xen 4.2.x through 4.4.x using shadow pagetables, a local HVM guest can trigger long-running memory-management work, consuming vCPU resources and potentially disrupting virtualization capacity. Exposure is limited to environments running Xen 4.2.x through 4.4.x with HVM guests and shadow pagetables. Public cloud, hosting, or multi-tenant virtualization platforms using those conditions have higher business relevance. Treat as a targeted infrastructure availability risk. It is not documented here as actively exploited, but affected multi-tenant Xen hosts could let one guest degrade service for others. Mitigation focus: Inventory Xen hypervisors and identify versions 4.2.x through 4.4.x.; Check Xen XSA-97 and distribution advisories for vendor-supported fixed packages.; Prioritize remediation on multi-tenant hosts or externally provided guest environments..
