{"id":"CVE-2026-90340","summary":"pinctrl: generic: free maps on pinctrl_generic_to_map() failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: generic: free maps on pinctrl_generic_to_map() failure\n\npinctrl_generic_to_map() parses DT configuration and allocates pinctrl\nmaps via pinctrl_utils_reserve_map().\n\nIf subsequent steps (such as pinctrl_utils_add_map_mux(),\npinctrl_generic_add_group(), pinconf_generic_parse_dt_config(), or\npinctrl_utils_add_map_configs()) return an error, *maps may contain\npartially allocated map entries. 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().","modified":"2026-09-18T03:48:37.783238524Z","published":"2026-09-17T16:08:51.635Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90340.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/09f47abc95ee9e819e7e93cd68c1c23abe11c842"},{"type":"WEB","url":"https://git.kernel.org/stable/c/17007cd700601777d9ee203a13d97e64ece3a10f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90340.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90340"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"aaaf31be04260316036f50a05b7d015c0d36b55a"},{"fixed":"09f47abc95ee9e819e7e93cd68c1c23abe11c842"},{"fixed":"17007cd700601777d9ee203a13d97e64ece3a10f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90340.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.2.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90340.json"}}],"schema_version":"1.9.0"}
