An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the \"/boot/\" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package."
