[Bug 1513540] Re: CVE-2015-5307

Sender: bounces@xxxxxxxxxxxxx
** 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.
