0 CVE-2023-4001 is an authentication bypass vulnerability in Red Hat Enterprise Linux 9's GRUB bootloader. The flaw arises from GRUB's reliance on device UUIDs to locate the configuration file containing the GRUB password hash. An attacker with physical access can attach a removable drive (e.g. , USB stick) with a duplicate UUID matching the system's /boot partition. On UEFI systems that enumerate removable drives before fixed drives, this allows bypassing GRUB password protection, potentially leading to full system compromise. This vulnerability was introduced by a downstream patch in Red Hat's grub2 and does not affect upstream grub2. The CVSS score is 6.8 (medium severity), reflecting high impact but requiring physical access and specific conditions. No known exploits are currently in the wild.
