Copyright © 2012 Red Hat, Inc. All rights reserved. Low 2026-05-27T00:00:00 kernel: ext2: reject inodes with zero i_nlink and valid mode in ext2_iget() 5.5 CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H CWE-1288

A flaw was found in the Linux kernel's ext2 filesystem. A local attacker could create a specially crafted filesystem image with malformed inodes (index nodes) that, when mounted, would not be properly rejected by the ext2_iget() function. This could lead to a kernel warning and potentially a system crash, resulting in a Denial of Service (DoS).
