Description OSIDB Bzimport 2025-02-26 03:19:03 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: atmel: Fix error handling in sam9x5_wm8731_driver_probe

The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.

This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error path.
