Although the\ninitial reply-size check includes a vendor count byte in the fixed layout,\nit does not guarantee that the byte remains after the standard codec array.\n\nIf a controller reply ends immediately after that array, calculating the\nvendor codec array size reads vnd_codecs->num beyond the skb data.  Use\nskb_pull_data() to validate and consume each codec header before using its\ncount in both command variants.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98247","source_modified_at":"2026-10-19T09:16:18.761Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"8961987f3f5fa2f2618e72304d013c8dd5e604a6","lessThan":"9c04b9a4d08b95dee901d24b7607c4cbd65fa0a8","status":"affected","versionType":"git"},{"version":"8961987f3f5fa2f2618e72304d013c8dd5e604a6","lessThan":"a6da782fefae611e68a1aa79644065fc8ca5abcd","status":"affected","versionType":"git"},{"version":"8961987f3f5fa2f2618e72304d013c8dd5e604a6","lessThan":"e4cfd3c4299105237458b27958bd7b0aa4c60795","status":"affected","versionType":"git"},{"version":"8961987f3f5fa2f2618e72304d013c8dd5e604a6","lessThan":"f49a543d76d48f184b34225d9c0e2fc4cbdea8ec","status":"affected","versionType":"git"},{"version":"8961987f3f5fa2f2618e72304d013c8dd5e604a6","lessThan":"12a82819b0cada6e304790b1097f8f9006eb6123","status":"affected","versionType":"git"},{"version":"8961987f3f5fa2f2618e72304d013c8dd5e604a6","lessThan":"d0795cfd6f655f4de84868a4f4bb41a03f037b3d","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98247","source_modified_at":"2026-10-19T09:16:18.761Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.16","status":"affected"},{"version":"0","lessThan":"5.16","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","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-2026-98247","source_modified_at":"2026-10-19T09:16:18.761Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"9c04b9a4d08b95dee901d24b7607c4cbd65fa0a8","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98247","source_modified_at":"2026-10-19T09:16:18.761Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"12a82819b0cada6e304790b1097f8f9006eb6123","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00205,"percentile":0.10027,"score_date":"2026-10-23"},"published_at":"2026-10-06T08:45:16.048Z","modified_at":"2026-10-19T09:16:18.761Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98247","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:16:18.761Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98247","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/9c04b9a4d08b95dee901d24b7607c4cbd65fa0a8"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/a6da782fefae611e68a1aa79644065fc8ca5abcd"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e4cfd3c4299105237458b27958bd7b0aa4c60795"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f49a543d76d48f184b34225d9c0e2fc4cbdea8ec"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/12a82819b0cada6e304790b1097f8f9006eb6123"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d0795cfd6f655f4de84868a4f4bb41a03f037b3d"}],"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":"2026-10-19T09:16:18.761Z","content_hash":"4760e94bbdc67a342b628819db926f689bb7156958ad35efa390adcdf3015acb"}}
