FKIE_CVE-2014-3690
Vulnerability from fkie_nvd - Published: 2014-11-10 11:55 - Updated: 2026-06-17 00:08
Severity
Summary
arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU.
