Details

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) HYPERCALLxenoprofop hypercalls, which are not properly handled in the doxenoprofop function in common/xenoprof.c, or (2) HYPERVISORxenpmuop hypercalls, which are not properly handled in the doxenpmuop function in arch/x86/cpu/vpmu.c.
