CVE-2014-3690 | BDVDB-2026-66106 Detail
Description#
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.
Impact#
No impact statement in the source data.
Weaknesses#
No weakness recorded in the source data.
