In the Linux kernel, the following vulnerability has been resolved:

regulator: core: fix unbalanced of node refcount in regulator_dev_lookup()

I got the the following report:

In of_get_regulator(), the node is returned from of_parse_phandle() with refcount incremented, after using it, of_node_put() need be called.
