Description

The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock).

Solution(s)

  • gentoo-linux-upgrade-app-emulations-xen
  • gentoo-linux-upgrade-app-emulations-xen-pvgrub
  • gentoo-linux-upgrade-app-emulations-xen-tools

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
