  Hello,

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.


Upstream patch:
