CVE-2014-0049 is a vulnerability of currently unknown severity. Buffer overflow in the complete_emulated_mmio function in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6 allows guest OS users to execute arbitrary code on the host OS by leveraging a loop that triggers an invalid memory copy affecting certain cancel_work_item data.. EPSS estimates a 0.77% chance of exploitation in the next 30 days.
