Description OSIDB Bzimport 2025-02-26 03:17:07 UTC 
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")
