CVE-2014-8480
Linux Kernel < 3.18 - Denial of Service via RIP-Relative Instruction Decoding
Title source: llmDescription
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.
