CVE-2016-9083 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. drivers/vfio/pci/vfio_pci.c in the Linux kernel through 4.8.11 allows local users to bypass integer overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a "state machine confusion bug.". EPSS estimates a 0.38% chance of exploitation in the next 30 days.
