    Added Description In the Linux kernel, the following vulnerability has been resolved:

    net: renesas: rswitch: avoid use-after-put for a device tree node

    The device tree node saved in the rswitch_device structure is used at
    several driver locations. So passing this node to of_node_put() after
    the first use is wrong.

    Move of_node_put() for this node to exit paths.
