CVE-2026-72349

The CVE-2026-72349 entry concerns the Linux kernel netfilter xt_rateest component. Affected function xt_rateest_mt() truncates 64-bit byte-rate values to 32-bit when the link exceeds ~34 Gbps, causing incorrect comparison results as the estimator rate can exceed 2^32-1 (~4.3 GB/s). The fix is to ...
