Vendor Workaround
Mitigation for this issue is to skip loading the affected module "nftables" onto the system until we have a fix available. This can be done by a blacklist mechanism that will ensure the driver is not loaded at boot time. ~~~ How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~
