Summary
In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd934x: Add missing of_node_put() in wcd934x_codec_parse_data The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This is similar to commit 64b92de9603f ("ASoC: wcd9335: fix a leaked reference by adding missing of_node_put")
