Description Johannes Segitz 2016-10-27 08:47:30 UTC

From: Vlad Tsyrklevich
    The vfio driver allows direct user access to devices. The
    VFIO_DEVICE_SET_IRQS ioctl for vfio PCI devices has a state machine
    confusion bug where specifying VFIO_IRQ_SET_DATA_NONE along with
    another bit in VFIO_IRQ_SET_DATA_TYPE_MASK in hdr.flags allows integer
    overflow checks to be skipped for hdr.start/hdr.count. This might
    allow memory corruption later in vfio_pci_set_msi_trigger() with user
    access to an appropriate vfio device file, but it seems difficult to
    usefully exploit in practice.

    https://patchwork.kernel.org/patch/9373631/


Use CVE-2016-9083 for the "state machine confusion bug."

Use CVE-2016-9084 for the separate problem fixed by "kzalloc is
changed to a kcalloc."
