CVE ID :CVE-2026-71219
Published : Sept. 3, 2026, 12:23 p.m. | 40 minutes ago
Description :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.
Severity: 4.7 | MEDIUM
