kernel is vulnerable to denial of service (DoS). The vulnerability exists as a flaw was found in the way KVM (Kernel-based Virtual Machine) 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.
