Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: possible module reference underflow in error path
dst->ops is set on when nft_expr_clone() fails, but module refcount has not been bumped yet, therefore nft_expr_destroy() leads to module reference underflow.
