✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Workaround: It is not possible to completely eliminate the theoretical risk of a remote exploit, but the attack is fairly complex and in many realistic deployments cannot be triggered from outside the local network. You can substantially reduce the likelihood of a successful attack by disabling network features that cause drivers to use the page_pool/zero-copy receive paths. The following commands are a conceptual example of mitigations — adapt them to your interface and driver: # replace eth0 with the actual interface name # turn off generic offloads that often change skb handling ethtool -K eth0 gro off lro off gso off tso off rx off # disable rx/tx offload flags separately: ethtool -K eth0 rxvlan off rxhash off # disable specific features (driver dependent) ethtool -k eth0
