Copyright © 2012 Red Hat, Inc. All rights reserved. Low 2026-04-24T00:00:00 kernel: xfs: scrub: unlock dquot before early return in quota scrub 5.5 CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H CWE-772

A flaw was found in the Linux kernel's XFS filesystem component. During quota scrubbing, the `xchk_quota_item` function could exit prematurely without releasing a critical lock. This can result in lock leaks or deadlocks in subsequent quota operations, potentially leading to system instability or a Denial of Service (DoS) condition.
