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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93215","source_modified_at":"2026-10-19T09:07:27.148Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d","lessThan":"88f4cd42a04bdadd189d7f667a4c279f4e962ca6","status":"affected","versionType":"git"},{"version":"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d","lessThan":"4cd24873ab9fdbd730604881a6e8087bc7b99336","status":"affected","versionType":"git"},{"version":"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d","lessThan":"7e9451bf0bdba6daee1eaf4e7566612af6ca1c32","status":"affected","versionType":"git"},{"version":"aeda33ab8160c7a2e24ba4f44492ad1e974ddc7d","lessThan":"6f4acc3a3c300e174e3f586b97b04ed8f5948c36","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93215","source_modified_at":"2026-10-19T09:07:27.148Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.8","status":"affected"},{"version":"0","lessThan":"6.8","status":"unaffected","versionType":"semver"},{"version":"6.12.109","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.50","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.4","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93215","source_modified_at":"2026-10-19T09:07:27.148Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"88f4cd42a04bdadd189d7f667a4c279f4e962ca6","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93215","source_modified_at":"2026-10-19T09:07:27.148Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4cd24873ab9fdbd730604881a6e8087bc7b99336","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93215","source_modified_at":"2026-10-19T09:07:27.148Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"7e9451bf0bdba6daee1eaf4e7566612af6ca1c32","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93215","source_modified_at":"2026-10-19T09:07:27.148Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6f4acc3a3c300e174e3f586b97b04ed8f5948c36","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05731,"score_date":"2026-10-23"},"published_at":"2026-09-24T15:10:37.863Z","modified_at":"2026-10-19T09:07:27.148Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93215","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:07:27.148Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93215","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/88f4cd42a04bdadd189d7f667a4c279f4e962ca6"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4cd24873ab9fdbd730604881a6e8087bc7b99336"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/7e9451bf0bdba6daee1eaf4e7566612af6ca1c32"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/6f4acc3a3c300e174e3f586b97b04ed8f5948c36"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:07:27.148Z","content_hash":"0874f91d18591b20645914c62fefc525aaa2867ba130ff5abefbe04e5be66b67"}}
