CyberRota Analysis
AI-GeneratedA vulnerability in the dracut error-handling function allows an attacker on an adjacent network to exploit improperly handled messages in the initramfs emergency-hook directory. This flaw can lead to command execution as root if the attacker controls a rogue DHCP server and injects malicious content into the DHCP ROOT_PATH option. Organizations using dracut should prioritize patching this vulnerability to mitigate the risk of unauthorized root access during boot-failure scenarios.

Original NVD Description
A flaw was found in dracut. 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.
