    Action Type Old Value New Value
    Added Description In the Linux kernel, the following vulnerability has been resolved:

    virtio-net: fix recursived rtnl_lock() during probe()

    The deadlock appears in a stack trace like:

    virtnet_probe()
    rtnl_lock()
    virtio_config_changed_work()
    netdev_notify_peers()
    rtnl_lock()

    It happens if the VMM sends a VIRTIO_NET_S_ANNOUNCE request while the
    virtio-net driver is still probing.

    The config_work in probe() will get scheduled until virtnet_open() enables
    the config change notification via virtio_config_driver_enable().
