CVE-2022-49668
In the Linux kernel, the following vulnerability has been resolved: PM / devfreq: exynos-ppmu: Fix refcount leak in of_get_devfreq_events of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: PM / devfreq: exynos-ppmu: Fix refcount leak in of_get_devfreq_events of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. This function only calls of_node_put() in normal path, missing it in error paths. Add missing of_node_put() to avoid refcount leak.
