Lars Bull reported a race condition in the PIT (programmable interrupt

kernel. A local guest user with access to PIT i/o ports could exploit this
flaw to cause a denial of service (crash) on the host. (CVE-2014-3611)

Lars Bull and Nadav Amit reported a flaw in how KVM (the Kernel Virtual
Machine) handles noncanonical writes to certain MSR registers. A privileged
guest user can exploit this flaw to cause a denial of service (kernel
panic) on the host. (CVE-2014-3610)");
