In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_limit: reject configurations that cause integer overflow
Reject bogus configs where internal token counter wraps around. This only
occurs with very very large requests, such as 17gbyte/s. Its better to
reject this rather than having incorrect ratelimit.
