Summary
A flaw was found in the Linux kernel's NTFS file system driver. When the driver attempts to reparent an index root, it can update metadata to reflect a larger size before the actual data structure is resized.
If this resize operation fails, the file system can enter an inconsistent state. This inconsistency can lead to file system corruption, potentially resulting in a denial of service or data integrity issues for a local user.
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-130.
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.
