CVE-2016-5242 is a vulnerability of currently unknown severity. The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion.. EPSS estimates a 0.34% chance of exploitation in the next 30 days.
