x86/HVM pinned cache attributes mis-handling
ISSUE DESCRIPTION To allow cachability control for HVM guests with passed through devices, an interface exists to explicitly override defaults which would otherwise be put in place. While not exposed to the affected guests themselves, the interface specifically exists for domains controlling such...

CVE-2022-42334
CVE-2022-42334 concerns the Xen hypervisor: a mis-handling in the HVM cache attributes interface used to override defaults for passed‑through devices. The root cause described across connected sources is unbounded control region creation and a lack of proper serialization for installation/removal...
