Description Prasad Pandit 2017-01-18 16:58:50 UTC
Linux kernel built with the Kernel-based Virtual Machine(CONFIG_KVM) support
is vulnerable to a use-after-free flaw. It could occur while creating devices,
via ioctl('/dev/kvm', ...) calls.

A user/process could use this flaw to crash the host kernel resulting in DoS
or potentially escalate their privileges on a system.
