** Description changed: - Ben Serebrin discovered that the KVM hypervisor implementation in the - Linux kernel did not properly catch Alignment Check exceptions. An - attacker in a guest virtual machine could use this to cause a denial of - service (system crash) in the host OS. + The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x + through 4.6.x, allows guest OS users to cause a denial of service (host + OS panic or hang) by triggering many #AC (aka Alignment Check) + exceptions, related to svm.c and vmx.c.
