Vulnerability from cvelistv5 – Published: 2026-09-03 12:23 – Updated: 2026-09-03 12:58

Title

Gfs2-utils: gfs2-utils: stack overflow via alloca(i_height) in metadata walk

Summary

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.

Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
