Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ath10k: Fix error handling in ath10k_setup_msa_resources 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 path.
