CVE-2016-9777 (GCVE-0-2016-9777)

Vulnerability from cvelistv5 – Published: 2016-12-28 07:42 – Updated: 2024-08-06 02:59
VLAI
Summary
KVM in the Linux kernel before 4.8.12, when I/O APIC is enabled, does not properly restrict the VCPU index, which allows guest OS users to gain host OS privileges or cause a denial of service (out-of-bounds array access and host OS crash) via a crafted interrupt request, related to arch/x86/kvm/ioapic.c and arch/x86/kvm/ioapic.h.
Severity
