{"schema":"threatline.record/2","record":{"id":"CVE-2026-98658","aliases":[],"summary":"iio: proximity: aw96103: validate firmware data length","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: proximity: aw96103: validate firmware data length\n\nThe firmware parser reads a length from the binary header and then uses\nit to walk six-byte register/value entries. A truncated firmware image\ncan make the parser read beyond the copied firmware buffer. A value\nsmaller than the four-byte count field also underflows, producing a very\nlarge length.\n\nRead the little-endian field with get_unaligned_le32(), as previously\nproposed by David Lechner. Validate the header size, reject an\nunderflowed length, ensure the resulting payload is contained in the\nfirmware image, and require it to contain whole register/value entries.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98658","source_modified_at":"2026-10-19T09:23:26.505Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"07b241262dcad07671c444ca955903325de28e9e","lessThan":"4a9b9f2d4e26589afd0ac099c8e5593170dd5ac7","status":"affected","versionType":"git"},{"version":"07b241262dcad07671c444ca955903325de28e9e","lessThan":"6501b032be217ecf47e793b78a05078cf0b604ad","status":"affected","versionType":"git"},{"version":"07b241262dcad07671c444ca955903325de28e9e","lessThan":"815ae0b73b69ace207b6bbf7ef428b06491c3ddb","status":"affected","versionType":"git"},{"version":"07b241262dcad07671c444ca955903325de28e9e","lessThan":"1a7c522a35477d70320bd64aba8e9de0c1058c6f","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98658","source_modified_at":"2026-10-19T09:23:26.505Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.12","status":"affected"},{"version":"0","lessThan":"6.12","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","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-2026-98658","source_modified_at":"2026-10-19T09:23:26.505Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4a9b9f2d4e26589afd0ac099c8e5593170dd5ac7","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98658","source_modified_at":"2026-10-19T09:23:26.505Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6501b032be217ecf47e793b78a05078cf0b604ad","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98658","source_modified_at":"2026-10-19T09:23:26.505Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"815ae0b73b69ace207b6bbf7ef428b06491c3ddb","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98658","source_modified_at":"2026-10-19T09:23:26.505Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"1a7c522a35477d70320bd64aba8e9de0c1058c6f","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.09314,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:44:12.196Z","modified_at":"2026-10-19T09:23:26.505Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98658","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:23:26.505Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98658","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/4a9b9f2d4e26589afd0ac099c8e5593170dd5ac7"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/6501b032be217ecf47e793b78a05078cf0b604ad"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/815ae0b73b69ace207b6bbf7ef428b06491c3ddb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/1a7c522a35477d70320bd64aba8e9de0c1058c6f"}],"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":"2026-10-19T09:23:26.505Z","content_hash":"813f1ba9383c93c1096bb40cc304ef6327bb3e3bd228137acba5206fd901e45d"}}
