Linux kernel ipset hash sets could misprocess address ranges

published 4 months ago
Summary

The Linux kernel's ipset feature for certain hash sets could continue scanning past the intended end of an IP address range. This could cause the system to handle network rules incorrectly. Updating the kernel fixes the loop so it stops exactly at the range limit, preventing unintended behavior.

What to do
  • Update echo linux to version 6.12.94-1.
