CVE-2018-10982: Debian Linux

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 7.0 only; version 8.0 only; version 9.0 only
• Xen Xen: up to and including 4.10.1
