CVE-2022-49241: ASoC: atmel: Fix error handling in sam9x5_wm8731_driver_probe
First published: Wed Feb 26 2025(Updated: )
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.
