The HVMOP_set_mem_type control in Xen 4.1 through 4.4.x allows local guest HVM administrators to cause a denial of service (hypervisor crash) or possibly execute arbitrary code by leveraging a separate qemu-dm vulnerability to trigger invalid page table translations for unspecified memory page types.

Security readout for executives and security teams

This Xen hypervisor flaw can let an administrator inside an HVM guest crash the host hypervisor, disrupting every virtual machine on that host. Sources also note possible arbitrary code execution, but only when combined with a separate qemu-dm vulnerability. Exposure is most likely on older Xen virtualization hosts running Xen 4.1 through 4.4.x with HVM guests, especially where guest administrators are customers, tenants, or otherwise less trusted than host administrators. Treat as high priority for legacy or multi-tenant Xen platforms because one guest administrator could affect host availability. Environments without affected Xen versions or without untrusted HVM guest admins have lower urgency, but should still verify patch status. Mitigation focus: Apply Xen XSA-92 or distribution security updates from trusted vendor advisories.; Upgrade affected Xen 4.1 through 4.4.x hosts where vendor patches are unavailable.; Prioritize multi-tenant or untrusted HVM guest environments..
