CVE-2026-72349

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

netfilter: xt_rateest: fix u64 truncation in xt_rateest_mt()

On links faster than ~34 Gbps, where byte rate may exceed 2^32-1
(~ 4.3 GBps), the comparison result becomes incorrect because the
truncated value no longer reflects the actual estimator rate.

Fix by changing the local variables to u64.
