During this process, with a line big enough it's possible to make this variable to overflow leading to a out-of-bounds write in the heap based buffer. This flaw may be leveraged to corrupt grub's internal critical data and secure boot bypass is not discarded as consequence.\n\ud83d\udccf Published: 2025-02-24T07:53:30.081Z\n\ud83d\udccf Modified: 2025-05-20T14:34:35.140Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/errata/RHSA-2025:6990\n2. https://access.redhat.com/security/cve/CVE-2025-0690\n3. https://bugzilla.redhat.com/show_bug.cgi?id=2346123\n4. https://lists.gnu.org/archive/html/grub-devel/2025-02/msg00024.html", "creation_timestamp": "2025-05-20T14:40:37.000000Z"}
