{"apiVersion":"1.0","identifier":"CVE-2026-72198","description":"In the Linux kernel, the following vulnerability has been resolved: ntfs: reject non-resident records for resident-only attributes The shared lookup-time attribute validator rejects non-resident $FILE_NAME and $VOLUME_NAME records because their formats require resident values and callers handle returned records as resident attributes. Other resident-only attribute types still pass through the generic non-resident mapping-pairs checks. That leaves real resident/non-resident union confusion paths. Inode load looks up $STANDARD_INFORMATION and then reads data.resident.value_offset without checking a->non_resident. ntfs_inode_sync_standard_information() does the same when updating the standard information value. ntfs_write_volume_flags() also looks up $VOLUME_INFORMATION and reads data.resident.value_offset directly. $INDEX_ROOT callers in dir.c and index.c depend on the same lookup contract before consuming the resident index root value. Reject non-resident records for all resident-only attribute types in the shared validator. Keep the existing $FILE_NAME and $VOLUME_NAME behavior, but factor it through a helper and extend it to $STANDARD_INFORMATION, $OBJECT_ID, $VOLUME_INFORMATION, $INDEX_ROOT, and $EA_INFORMATION. For $OBJECT_ID and $EA_INFORMATION this is contract hardening for resident-only formats; this patch only rejects the non-resident form and does not add new resident value validation for those types.","publishedAt":"2026-08-15T06:21:38","lastModifiedAt":"2026-08-19T08:17:13","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72198","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00162,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72198","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72198","en":"https://www.redsauce.net/en/cves/CVE-2026-72198","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72198","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72198","de":"https://www.redsauce.net/de/cves/CVE-2026-72198","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72198","el":"https://www.redsauce.net/el/cves/CVE-2026-72198"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72198"}}
