Name of the Vulnerable Software and Affected Versions
Xen versions prior to 4.11.x
Description
The issue is caused by synchronization errors when using a shared resource, allowing an attacker to cause a denial of service or gain privileges by leveraging a page-writability race condition during the addition of a passed-through PCI device.
Recommendations
For Xen versions prior to 4.11.x, consider restricting the addition of passed-through PCI devices to minimize the risk of exploitation until a patch is available.
As a temporary workaround, consider disabling the functionality related to the addition of PCI devices with pass-through functionality until a fix is provided.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
