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.

This update includes the following RPMs: dracut: * dracut-109-7.hum1 (aarch64, x86_64) * dracut-caps-109-7.hum1 (aarch64, x86_64) * dracut-config-generic-109-7.hum1 (aarch64, x86_64) * dracut-config-rescue-109-7.hum1 (aarch64, x86_64) * dracut-live-109-7.hum1 (aarch64, x86_64) * dracut-network-109-7.hum1 (aarch64, x86_64) * dracut-squash-109-7.hum1 (aarch64, x86_64) * dracut-tools-109-7.hum1 (aarch64, x86_64) * dracut-109-7.hum1.src (src)
