NVD Description

Note: Versions mentioned in the description apply only to the upstream dracut package and not the dracut package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP options, such as a malicious root-path, next-server, or bootfile name, to a system using dracut's NetworkManager-based initrd network module. These options are improperly handled and written into a temporary shell script without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs during system boot.
