Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: media: v4l2-core: Fix a potential resource leak in v4l2_fwnode_parse_link() If fwnode_graph_get_remote_endpoint() fails, 'fwnode' is known to be NULL, so fwnode_handle_put() is a no-op. Release the reference taken from a previous fwnode_graph_get_port_parent() call instead. Also handle fwnode_graph_get_port_parent() failures. In order to fix these issues, add an error handling path to the function and the needed gotos.
