CVE-2018-10982 is a vulnerability of currently unknown severity. An issue was discovered in Xen through 4.10.x allowing x86 HVM guest OS users to cause a denial of service (unexpectedly high interrupt number, array overrun, and hypervisor crash) or possibly gain hypervisor privileges by setting up an HPET timer to deliver interrupts in IO-APIC mode, aka vHPET interrupt injection.. EPSS estimates a 0.49% chance of exploitation in the next 30 days.
