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. (NVD)
