CVE-2026-71219

4.7 mediumEPSS 0.1%

Medium (4.7) in redhat enterprise linux. EPSS 0.1% chance of exploitation in the next 30 days.

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.
