The emulation routines for unspecified X86 devices in Xen 3.2.x through 4.5.x does not properly initialize data, which allow local HVM guest users to obtain sensitive information via vectors involving an unsupported access size.

Security readout for executives and security teams

CVE-2015-2044 is an information disclosure flaw in Xen HVM device emulation. A user inside a guest VM could potentially read sensitive data because some emulation routines did not properly initialize data for unsupported access sizes. Exposure is most likely on legacy Xen virtualization hosts running Xen 3.2.x through 4.5.x with HVM guests. Multi-tenant or untrusted guest environments carry the highest business concern. Treat as a legacy virtualization isolation issue. Prioritize if old Xen infrastructure still hosts untrusted or customer-controlled VMs; otherwise handle through legacy platform cleanup. Mitigation focus: Identify Xen hosts and versions, especially 3.2.x through 4.5.x.; Check Xen XSA-121 and vendor advisories for supported fixed packages.; Apply relevant hypervisor or distribution updates through normal maintenance channels..
