The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.</p> <p><strong>Affected:</strong> Ubuntu:Pro:16.04:LTS: dracut, Ubuntu:Pro:18.04:LTS: dracut, Ubuntu:Pro:20.04:LTS: dracut, Ubuntu:Pro:22.04:LTS: dracut, Ubuntu:24.04:LTS: dracut, Ubuntu:26.04:LTS: dracut</p> <p>A flaw was found in dracut.
