CVE-2019-19332

Priority
Description
An out-of-bounds memory write issue was found in the Linux Kernel, version
3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the
'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by
the KVM hypervisor. A user or process able to access the '/dev/kvm' device
could use this flaw to crash the system, resulting in a denial of service.
Ubuntu-Description
It was discovered that the KVM hypervisor implementation in the Linux
kernel did not properly handle ioctl requests to get emulated CPUID
features. An attacker with access to /dev/kvm could use this to cause a
denial of service (system crash).
