  1. CVE-2026-43198 Linux TCP IPv6 Race Fix: Why Ordering Matters for Fleets

    CVE-2026-43198 is a Linux kernel TCP/IPv6 race-condition flaw disclosed by kernel.org and published in NVD on May 6, 2026, involving tcp_v6_syn_recv_sock(), where a newly created child socket can become visible to other CPUs before its IPv6 state is fully initialized. That sounds like an obscure...
