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

staging: media: tegra-video: fix device_node use after free

At probe time this code path is followed:

* tegra_csi_init * tegra_csi_channels_alloc * for_each_child_of_node(node, channel) -- iterates over channels * automatically gets 'channel' * tegra_csi_channel_alloc() * saves into chan->of_node a pointer to the channel OF node * automatically gets and puts 'channel' * now the node saved in chan->of_node has refcount 0, can disappear * tegra_csi_channels_init * iterates over channels * tegra_csi_channel_init -- uses chan->of_node

After that, chan->of_node keeps storing the node until the device is removed.

of_node_get() the node and of_node_put() it during teardown to avoid any risk.
