Vulnerability description

DayBreach CVE AI Research

CVE-2026-71219 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca() with an exponentially-derived size from the untrusted on-disk di_depth field without bounds validation. A crafted GFS2 filesystem image with a large di_depth value causes stack exhaustion and a denial of service when processed by fsck.gfs2, gfs2_edit, or savemeta.
