CVE-2013-4553 is a vulnerability of currently unknown severity. The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock).. EPSS estimates a 0.56% chance of exploitation in the next 30 days.
