Severity Medium

Affected Packages 1

CVEs 1

Problem Description:
Some OSes (including 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 unbound, a guest may be able to trigger a OOM in
the backend.
