Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) before 4.14.6, 4.9.69, 4.4.106, 3.18.88, 3.16.52 and 3.2.97 is vulnerable to a denial of service issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in denial of service.
