The msr_mtrr_valid function in arch/x86/kvm/mtrr.c in the Linux kernel before 4.6.1 supports MSR 0x2f8, which allows guest OS users to read or write to the kvm_arch_vcpu data structure, and consequently obtain sensitive information or cause a denial of service (system crash), via a crafted ioctl call.

Security readout for executives and security teams

CVE-2016-3713 is a Linux KVM kernel flaw in versions before 4.6.1. A user inside a guest OS could interact with an invalid MSR path and affect KVM host memory, potentially exposing sensitive data or crashing the system. Exposure is most relevant to x86 Linux hosts running KVM with kernels before 4.6.1 or vendor kernels lacking the referenced backport. Non-KVM systems are not indicated as affected by the provided sources. Treat this as a high-priority virtualization-host patching issue where KVM runs untrusted or multi-tenant guests. Business impact is mainly host crash risk and potential sensitive data exposure across virtualization boundaries. Mitigation focus: Upgrade affected Linux KVM hosts to kernel 4.6.1 or a vendor-fixed backport.; Check distribution advisories for the commit 9842df62004f366b9fed2423e24df10542ee0dc5.; Prioritize multi-tenant or untrusted-guest virtualization hosts..
