CVE-2014-8480: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 0.6% chance of exploitation in the next 30 days.

The instruction decoder in arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel before 3.18-rc2 lacks intended decoder-table flags for certain RIP-relative instructions, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via a crafted application.

Affected products

• Linux Linux Kernel: up to and including 3.18
