Summary
A flaw was found in the Linux kernel's NTFS file system driver. A missing bounds check when processing Extended Attribute (EA) entries in the `ntfs_ea_lookup` and `ntfs_listxattr` functions could allow a local attacker to craft a malicious NTFS file system.
When this file system is mounted, it could lead to an out-of-bounds read, potentially causing a system crash (Denial of Service) or information disclosure. 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-125. 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.
