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 &#34;/boot/&#34; 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&#39;s version of grub2 and does not affect the upstream package.</p> <p><strong>Affected:</strong> Red Hat Enterprise Linux 9, Red Hat Enterprise Linux 9.0 Extended Update Support, Red Hat Enterprise Linux 9.2 Extended Update Support, Red Hat Enterprise Linux 8</p> <p>An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature.
