The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock).

Security readout for executives and security teams

CVE-2013-4553 is a Xen hypervisor flaw that can let an administrator inside a guest VM hang the host. The business risk is service outage, not data theft, based on the supplied sources. Exposure is most likely on legacy Xen hosts running the cited versions, especially where VM administrators are tenants, customers, contractors, or otherwise not fully trusted. Treat as a targeted availability risk for legacy Xen infrastructure. Prioritize remediation when affected hosts support production, multi-tenant, or customer-managed virtual machines. Mitigation focus: Inventory Xen hypervisors and identify versions 3.4.x through 4.3.x.; Apply relevant Xen or distribution security updates from vendor advisories.; Prioritize hosts running untrusted or multi-tenant guest workloads..
