Created: Dec 1, 2014    Updated: Dec 3, 2018
Resolved Date: Jan 30, 2015
Found In Version: 6.0.0.13
Fix Version: 6.0.0.17
Severity: Standard
Applicable for: Wind River Linux 6
Component/s: Kernel

Description

The instruction decoder in arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel before 3.18-rc2 does not properly handle invalid instructions, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via a crafted application that triggers (1) an improperly fetched instruction or (2) an instruction that occupies too many bytes.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-8480.
