CVE ID:	CVE-2020-29568
Description:	An issue was discovered in Xen through 4.14.x. Some OSes (such as Linux, FreeBSD, and NetBSD) are processing watch events using a single thread. If the events are received faster than the thread is able to handle, they will get queued. As the queue is unbounded, a guest may be able to trigger an OOM in the backend. All systems with a FreeBSD, Linux, or NetBSD (any version) dom0 are vulnerable.
Test IDs:	1.3.6.1.4.1.25623.1.0.892557   1.3.6.1.4.1.25623.1.0.892586   1.3.6.1.4.1.25623.1.0.704843
