{"id":"CVE-2024-45779","details":"An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash.","modified":"2026-03-11T07:44:57.320300Z","published":"2025-03-03T15:15:14.660Z","related":["SUSE-SU-2025:01961-1","SUSE-SU-2025:0586-1","SUSE-SU-2025:0587-1","SUSE-SU-2025:0588-1","SUSE-SU-2025:0607-1","SUSE-SU-2025:0629-1","SUSE-SU-2025:20511-1","SUSE-SU-2025:20863-1","openSUSE-SU-2025:14822-1"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2024-45779"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2345854"},{"type":"ARTICLE","url":"https://lists.gnu.org/archive/html/grub-devel/2025-02/msg00024.html"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"2.12"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-45779.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:H"}]}
