When reading an HFS volume's name at grub_fs_mount(), the HFS filesystem driver performs a strcpy() using the user-provided volume name as input without properly validating the volume name's length. This issue may read to a heap-based out-of-bounds writer, impacting grub's sensitive data integrity and eventually leading to a secure boot protection bypass.","epss":{"date":"2026-11-04","percentile":0.13398,"score":0.00226},"exploits":[],"kev":null,"metrics":[{"score":7.8,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793883073952,"publishedAt":1741021525397,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2024-45782"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2345858"}],"remediation":[],"revision":"5d937a5b0ee13af257bf6baf7feab5f717ac33c91dd4865292fe135fdb5a11bc","sources":[{"modifiedAt":1793883073952,"name":"CNA: redhat","retrievedAt":1793884153301,"url":"https://www.cve.org/CVERecord?id=CVE-2024-45782"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793884200384,"url":"https://api.first.org/data/v1/epss?cve=CVE-2024-45782"}],"ssvc":{"assessedAt":1741104997826,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Grub2: fs/hfs: strcpy() using the volume name (fs/hfs.c:382)","updatedAt":1793884200384}
