nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel
before 5.12.13 allows local users to cause a denial of service (NULL
pointer dereference and general protection fault) because of the missing
initialization for nft_set_elem_expr_alloc. A local user can set a
netfilter table expression in their own namespace.
