CVE-2026-42487

HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model via XENDOMCTLioportmapping, and hence the linked list used may changed at any time. Traversal of those lists while handling guest I/O port accesses therefore needs...

CVE-2026-42487

CVE-2026-42487 concerns the Xen hypervisor’s handling of x86 HVM I/O port list traversal. The root cause stated in the sources is that traversal of the linked list used for guest I/O port accesses requires synchronization with updates to the translation/mapping (XEN_DOMCTL_ioport_mapping), but th...
