This\nleaves a dangling pointer in the array. Then cdx_destroy_res_attr()\nfrees the already-freed memory. Fix the double free by initializing\ncdx_dev->res_attr[num] after sysfs_create_bin_file() completes.","state":0,"publishedAt":"2026-09-24T15:10:37.863+00:00","modifiedAt":"2026-10-19T09:07:27.148+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/cdx/cdx.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d\",\n                            \"lessThan\": \"88f4cd42a04bdadd189d7f667a4c279f4e962ca6\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d\",\n                            \"lessThan\": \"4cd24873ab9fdbd730604881a6e8087bc7b99336\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d\",\n                            \"lessThan\": \"7e9451bf0bdba6daee1eaf4e7566612af6ca1c32\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d\",\n                            \"lessThan\": \"6f4acc3a3c300e174e3f586b97b04ed8f5948c36\",\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/cdx/cdx.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.8\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.109\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.50\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.4\",\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/88f4cd42a04bdadd189d7f667a4c279f4e962ca6","https://git.kernel.org/stable/c/4cd24873ab9fdbd730604881a6e8087bc7b99336","https://git.kernel.org/stable/c/7e9451bf0bdba6daee1eaf4e7566612af6ca1c32","https://git.kernel.org/stable/c/6f4acc3a3c300e174e3f586b97b04ed8f5948c36"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93215","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93215","identifiers":["CVE-2026-93215"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
