✅ 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 Workaround: If ETS (Enhanced Transmission Selection) scheduler not being used, then the mitigation would be to disabled related Kernel module. To mitigate this issue, prevent module sch_ets from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically. sch_ets Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
