  "title": "ntfs: reject non-resident records for resident-only attributes",
  "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-\u003Enon_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.",
