Lifecycle Timeline
1DescriptionCVE.org
A stack overflow vulnerability was found in gfs2-utils. The metadata walk code in metawalk.c uses alloca() with an untrusted inode height value from on-disk metadata without bounds validation, causing stack exhaustion and a denial of service when processing crafted GFS2 filesystem images.
AnalysisAI
Stack exhaustion in gfs2-utils's metawalk.c metadata walk code allows a local attacker to cause denial of service by supplying a crafted GFS2 filesystem image containing a maliciously large inode height value that drives unbounded alloca() calls. Affected systems include Red Hat Enterprise Linux 7, 8, and 9 with gfs2-utils installed; the CVSS 4.7 medium rating reflects a local, high-complexity, user-interaction-required attack path with no confidentiality or integrity impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a user or automated process actively invoke a gfs2-utils tool (such as fsck.gfs2 or gfs2_edit) against an attacker-controlled GFS2 filesystem image, satisfying the UI:R user-interaction requirement from the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | With a CVSS base score of 4.7 and vector AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H, this vulnerability presents limited real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Monitor https://access.redhat.com/security/cve/CVE-2026-71224 and apply updated gfs2-utils packages from Red Hat once released; no specific patched package version is identified in the currently available advisory data. … Detailed patch versions, workarounds, and compensating controls in full report. |
