CVE-2022-49477 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ASoC: samsung: Fix refcount leak in aries_audio_probe

of_parse_phandle() returns a node pointer with refcount incremented we should use of_node_put() on it when done. If extcon_find_edev_by_node() fails it doesn’t call of_node_put() Calling of_node_put() after extcon_find_edev_by_node() to fix this.
