In the Linux kernel, the following vulnerability has been resolved: media: v4l2-fwnode: Fix fwnode leak in v4l2_fwnode_parse_link In v4l2_fwnode_parse_link(), the remote endpoint fwnode reference is acquired using fwnode_graph_get_remote_endpoint(). This reference is properly released in the error paths, but it is leaked on the success path. Add the missing fwnode_handle_put() before returning 0 to prevent the reference leak.
