CVE-2022-49241
5.5
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.
