Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: pinctrl: generic: free maps on pinctrl_generic_to_map() failure pinctrl_generic_to_map() parses DT configuration and allocates pinctrl maps via pinctrl_utils_reserve_map(). If subsequent steps (such as pinctrl_utils_add_map_mux(), pinctrl_generic_add_group(), pinconf_generic_parse_dt_config(), or pinctrl_utils_add_map_configs()) return an error, *maps may contain partially allocated map entries. Returning the error directly without freeing *maps leaks the allocated mapping memory across all drivers that rely on pinctrl_generic_to_map(). Fix this by calling pinctrl_utils_free_map() and resetting *maps, *num_maps, and *num_reserved_maps in the error path of pinctrl_generic_to_map().
