qemu may drive Xen into unbounded loop

ISSUE DESCRIPTION When Xen sends requests to a device model, the next expected action inside Xen is tracked using a state field. The requests themselves are placed in a memory page shared with the device model, so that the device model can communicate to Xen its progress on the request. The state...

x86 vHPET interrupt injection errors

ISSUE DESCRIPTION The High Precision Event Timer HPET can be configured to deliver interrupts in one of three different modes - through legacy interrupts; through the IO-APIC; or optionally via a method similar to PCI MSI. The last mode is optional and not implemented by Xen. However, of the firs...

CVE-2018-10472

Xen CVE-2018-10472 affects Xen up to 4.10.x. In certain configurations, an x86 HVM guest OS user could read arbitrary dom0 files by live-inserting a CDROM via QMP and targeting the CDROM as the backing file of a snapshot. This allows partial information disclosure from dom0 to the guest. The desc...
