Description OSIDB Bzimport 2025-06-18 12:09:59 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoc: audio-graph-card2: Fix refcount leak bug in __graph_get_type()

We should call of_node_put() for the reference before its replacement
as it returned by of_get_parent() which has increased the refcount.
Besides, we should also call of_node_put() before return.
