{"id":"AZL-99906","summary":"CVE-2026-71219 affecting package gfs2-utils 3.5.1-1","details":"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.","modified":"2026-09-14T05:26:59Z","published":"2026-09-03T13:06:02Z","upstream":["CVE-2026-71219"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71219"}],"affected":[{"package":{"name":"gfs2-utils","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/gfs2-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.5.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99906.json"}}],"schema_version":"1.9.0"}
