Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to "deep page table traversal."

Security readout for executives and security teams

This Xen issue lets a local paravirtualized guest kernel tie up long-running hypervisor page-table work, causing a denial of service. The business risk is service availability on older Xen virtualization hosts, especially where tenants or workloads are not fully trusted. Exposure is most likely on legacy Xen hosts running paravirtualized guests, particularly Xen 4.1.x, 4.2.x, or earlier. The bundle does not identify non-Xen products or affected CPEs. Prioritize remediation for shared or multi-tenant Xen environments because one guest could affect availability for others. Isolated lab or fully trusted single-tenant hosts are lower urgency, but unsupported Xen should still be retired. Mitigation focus: Inventory Xen hypervisors and identify 4.1.x, 4.2.x, or earlier deployments.; Check Xen and distribution advisories for the applicable security update.; Apply vendor-provided Xen packages from Debian, Fedora, Gentoo, SUSE, or your platform vendor..
