Returning the error directly without\nfreeing *maps leaks the allocated mapping memory across all drivers\nthat rely on pinctrl_generic_to_map().\n\nFix this by calling pinctrl_utils_free_map() and resetting *maps,\n*num_maps, and *num_reserved_maps in the error path of\npinctrl_generic_to_map().","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/09f47abc95ee9e819e7e93cd68c1c23abe11c842","tags":[]},{"url":"https://git.kernel.org/stable/c/17007cd700601777d9ee203a13d97e64ece3a10f","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
