{"schema":"threatline.record/2","record":{"id":"CVE-2026-98931","aliases":[],"summary":"mtd: spinand: fix NULL pointer dereference with no ECC engine","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: spinand: fix NULL pointer dereference with no ECC engine\n\nWhen \"nand-no-ecc-engine\" is set in DT, nanddev_get_ecc_engine() takes\nthe NAND_ECC_ENGINE_TYPE_NONE path and returns success while leaving\nnand->ecc.engine NULL. The SPI-NAND code nevertheless dereferences it\nunconditionally to test for a pipelined engine, so probing such a\ndevice oopses immediately.\n\nRather than open-coding the test three times, add a\nnand_ecc_is_pipelined() helper to the NAND core that folds the NULL\ncheck into the integration comparison, and use it everywhere. Future\ncallers then cannot reintroduce the problem.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98931","source_modified_at":"2026-10-23T12:11:34.935Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"77c449c9c946fc420008dc55cd30f53749c915e4","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"3c765fd5212c1bbc71568b1518a7ec963a7040b4","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"80e8b0ea73ba295e92dfb6cf1c41df9da64234c6","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"fc2f651f520394893b14b75281a01e502bfa73bb","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"b890e6163761ddb580cc74f43e15f8bbde15647e","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98931","source_modified_at":"2026-10-23T12:11:34.935Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.18","status":"affected"},{"version":"0","lessThan":"5.18","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","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-2026-98931","source_modified_at":"2026-10-23T12:11:34.935Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"77c449c9c946fc420008dc55cd30f53749c915e4","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98931","source_modified_at":"2026-10-23T12:11:34.935Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"3c765fd5212c1bbc71568b1518a7ec963a7040b4","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98931","source_modified_at":"2026-10-23T12:11:34.935Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"80e8b0ea73ba295e92dfb6cf1c41df9da64234c6","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T12:11:34.935Z","modified_at":"2026-10-23T12:11:34.935Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98931","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:11:34.935Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/77c449c9c946fc420008dc55cd30f53749c915e4"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/3c765fd5212c1bbc71568b1518a7ec963a7040b4"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/80e8b0ea73ba295e92dfb6cf1c41df9da64234c6"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/fc2f651f520394893b14b75281a01e502bfa73bb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b890e6163761ddb580cc74f43e15f8bbde15647e"}],"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":"2026-10-23T12:11:34.935Z","content_hash":"e4cab9588ebbbdc68731c0a0af906d516773423c32045bcff3285ff0d5f5fe16"}}
