CVE-2026-42487
The Xen hypervisor is vulnerable to an x86 HVM I/O port list traversal issue (XSA-491 ). The root cause is a lack of synchronization during the traversal of linked lists used for guest I/O port translations, which are managed by the device model via XEN_DOMCTL_ioport_mapping and can change at any...
CVE-2026-42487: Undefined Security Weakness
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-2026-23558: Concurrent Execution using Shared Resource with Improper Synchronization
The adjustments made for XSA-379 as well as those subsequently becoming XSA-387 still left a race window, when a HVM or PVH guest does a grant table version change from v2 to v1 in parallel with mapping the status pages via XENMEMaddtophysmap. Some of the status pages may then be freed while...
PT-2026-27499
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Xen privcmd driver allows user space processes to issue arbitrary hypercalls. Normally, access is limited to root and the hypervisor denies hypercalls affecting other domains. Howeve...
CVE-2025-58149: Operation on a Resource after Expiration or Release
When passing through PCI devices, the detach logic in libxl won't remove access permissions to any 64bit memory BARs the device might have. As a result a domain can still have access any 64bit memory BAR when such device is no longer assigned to the domain. For PV domains the permission leak allo...
