CVE-2026-13734 Zephyr WireGuard mutates peer state before anti-replay check, enabling capture-replay endpoint hijack

Zephyr's WireGuard VPN data-plane receive handler wgprocessdatamessage in subsys/net/lib/wireguard/wgcrypto.c validated the anti-replay counter too late. After AEAD decryption of a MESSAGETRANSPORTDATA packet succeeded, the code committed several peer-state changes — updatepeeraddr endpoint roami...
