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().","state":0,"publishedAt":"2026-09-17T16:08:51.635+00:00","modifiedAt":"2026-10-19T09:01:57.296+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/pinctrl/pinctrl-generic.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"aaaf31be04260316036f50a05b7d015c0d36b55a\",\n                            \"lessThan\": \"09f47abc95ee9e819e7e93cd68c1c23abe11c842\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"aaaf31be04260316036f50a05b7d015c0d36b55a\",\n                            \"lessThan\": \"17007cd700601777d9ee203a13d97e64ece3a10f\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/pinctrl/pinctrl-generic.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.2\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/09f47abc95ee9e819e7e93cd68c1c23abe11c842","https://git.kernel.org/stable/c/17007cd700601777d9ee203a13d97e64ece3a10f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90340","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90340","identifiers":["CVE-2026-90340"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
