Xen 3.2.x through 4.6.x does not limit the number of printk console
messages when logging certain pmu and profiling hypercalls, which allows
local guests to cause a denial of service via a sequence of crafted (1)
HYPERCALL_xenoprof_op hypercalls, which are not properly handled in the
do_xenoprof_op function in common/xenoprof.c, or (2) HYPERVISOR_xenpmu_op
hypercalls, which are not properly handled in the do_xenpmu_op function in
arch/x86/cpu/vpmu.c.
