Description Prasad J 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.

This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5, 6, 7 and Red Hat Enterprise MRG 2.

This issue was corrected in 4.8.13 kernels available across all current fedora releases on 2016-12-12.
