Summary
In the Linux kernel, the following vulnerability has been resolved: drm/meson: Fix refcount bugs in meson_vpu_has_available_connectors() In this function, there are two refcount leak bugs: (1) when breaking out of for_each_endpoint_of_node(), we need call the of_node_put() for the 'ep'; (2) we should call of_node_put() for the reference returned by of_graph_get_remote_port() when it is not used anymore.
