Subject: CVE-2019-19332 Kernel: kvm: OOB memory write via
kvm_dev_ioctl_get_cpuid
Hello,
An out-of-bounds memory write issue was found in the way Linux kernel's KVM
hypervisor handled 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get cpuid
features emulated by the KVM hypervisor. A user/process able to access
'/dev/kvm' device could use this flaw to crash the system resulting in DoS
issue.
It was found by Syzkaller

'CVE-2019-19332' was assigned by Red Hat Inc.
