KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for the standard Red Hat Enterprise Linux kernel.

A flaw was found in the way QEMU-KVM handled the reloading of fs and gs segment registers when they had invalid selectors. A privileged host user with access to '/dev/kvm' could use this flaw to crash the host (denial of service). (CVE-2010-3698)
