Summary
In the Linux kernel, the following vulnerability has been resolved: ntfs: not change 0-byte $DATA attribute to non-resident When ntfs_resident_attr_resize() cannot grow a resident attribute in place, it retries after converting other resident attributes to non-resident to free space in the MFT recrord.
Do not select zero-length resident $DATA attributes for this conversion. fsck treats 0-byte non-resident $DATA attribute as corruptions. A flaw was found in the NTFS file system driver in the Linux kernel.
When the ntfs_resident_attr_resize() function attempts to free space by converting resident attributes to non-resident, it incorrectly selects zero-length $DATA attributes for this conversion. This can lead to fsck (file system check) treating these 0-byte non-resident $DATA attributes as corruptions, potentially resulting in file system integrity issues.
Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-915.
Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
