Subject: CVE request Kernel: kvm: use-after-free issue while creating


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:


Thank you.
