Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8192-mt6359: Fix error handling in mt8192_mt6359_dev_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 paths.
Fix this by calling of_node_put() in error handling too.
Affected configurations
• linux linux kernel (>= 5.15.17 < 5.15.33)
• linux linux kernel (>= 5.16.3 < 5.16.19)
• linux linux kernel (>= 5.17 < 5.17.2)
