CVE-2015-8338
Last modified
CVE-2015-8338 is a vulnerability of currently unknown severity. Xen 4.6.x and earlier does not properly enforce limits on page order inputs for the (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange, and possibly other HYPERVISOR_memory_op suboperations, which allows ARM guest OS administrators to cause a denial of service (CPU consumption, guest reboot, or watchdog timeout and host reboot) and possibly have unspecified other impact via unknown vectors.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
