How to fix?

There is no fixed version for RHEL:7 kernel-bootwrapper.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: set dormant flag on hook register failure

We need to set the dormant flag again if we fail to register the hooks.

During memory pressure hook registration can fail and we end up with a table marked as active but no registered hooks.

On table/base chain deletion, nf_tables will attempt to unregister the hook again which yields a warn splat from the nftables core.
