CVE-2026-43198

CVE-2026-43198 is a Linux kernel race in IPv6 TCP socket handling. The issue occurs in tcp_v6_syn_recv_sock() where the child socket becomes visible before IPv6 state is initialized, allowing other CPUs to access it and potentially triggering instability. The fix moves the problematic code into t...
