✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To mitigate this issue, ensure that systems configured to obtain network settings via DHCP in the initramfs are only booted on trusted networks. This vulnerability requires an attacker to control a DHCP server on the adjacent network segment. If network configuration via DHCP is not strictly necessary during the initramfs phase, consider using static network configuration.
