Code execution via undersized network-config buffer
Published Feb 19, 2025 · Updated Aug 31, 2026
Out-of-bounds write in GNU GRUB 2.12 and earlier allows remote attackers on the same network segment to execute code during network boot. grub_net_search_config_file() allocates an internal buffer without accounting for a user-controlled environment variable's length, then copies it with grub_strcpy(). Exploitation requires network boot on an attacker-influenced segment and can bypass Secure Boot protections.
