How to fix?

There is no fixed version for Centos:10 kernel-64k-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-core package and not the kernel-64k-core package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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

netfilter: bridge: release template ct on non-IP path

A bridge nftables ct zone set rule can attach a conntrack template to an skb before nf_ct_bridge_pre() sees it. For non-IPv4 and non-IPv6 EtherTypes, nf_ct_bridge_pre() currently overwrites skb->_nfct with IP_CT_UNTRACKED without releasing the existing template reference.

That makes the per-cpu template, and any temporary templates allocated for concurrent use, unreachable and leaks memory until the host runs out of slab.

Reset the skb conntrack state before marking the frame untracked so the existing template reference is dropped on the non-IP path.
