{"cve":"CVE-2026-72198","nvd":{"published":"2026-08-15T06:21:38.440","modified":"2026-10-21T13:19:33.450","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: reject non-resident records for resident-only attributes\n\nThe shared lookup-time attribute validator rejects non-resident\n$FILE_NAME and $VOLUME_NAME records because their formats require\nresident values and callers handle returned records as resident\nattributes. Other resident-only attribute types still pass through the\ngeneric non-resident mapping-pairs checks.\n\nThat leaves real resident/non-resident union confusion paths. Inode load\nlooks up $STANDARD_INFORMATION and then reads data.resident.value_offset\nwithout checking a->non_resident. ntfs_inode_sync_standard_information()\ndoes the same when updating the standard information value.\nntfs_write_volume_flags() also looks up $VOLUME_INFORMATION and reads\ndata.resident.value_offset directly. $INDEX_ROOT callers in dir.c and\nindex.c depend on the same lookup contract before consuming the resident\nindex root value.\n\nReject non-resident records for all resident-only attribute types in the\nshared validator. Keep the existing $FILE_NAME and $VOLUME_NAME behavior,\nbut factor it through a helper and extend it to\n$STANDARD_INFORMATION, $OBJECT_ID, $VOLUME_INFORMATION, $INDEX_ROOT, and\n$EA_INFORMATION. For $OBJECT_ID and $EA_INFORMATION this is contract\nhardening for resident-only formats; this patch only rejects the\nnon-resident form and does not add new resident value validation for\nthose types.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/097cdfd0a55df5af82c9753833f39a8bfadbcfcb","https://git.kernel.org/stable/c/6626fb859f4c4772f2f59751d23937716e03f98f","https://git.kernel.org/stable/c/7ffa8f3d30236e0ab897c30bdb01224ff1fe1c89","https://git.kernel.org/stable/c/b54c9beb90e570bae17a9c18442aeeaf17165ccb"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-72198","score":0.00175,"percentile":0.06967,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
