{"id":"CVE-2024-45776","details":"When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections.","modified":"2026-03-23T05:31:58.316670Z","published":"2025-02-18T20:15:19Z","related":["ALSA-2025:16154","ALSA-2025:6990","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/errata/RHSA-2025:16154"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:6990"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2339182"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2024-45776"}],"schema_version":"1.7.5"}
