Kerentanan Allocation of Resources Without Limits or Throttling pada xen, debian linux. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

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.
