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...

CVE-2026-13734

Zephyr RTOS's WireGuard data-plane receive handler wg_process_data_message() in subsys/net/lib/wireguard/wg_crypto.c validated the anti-replay counter only after committing several peer-state mutations (endpoint roaming update, liveness timers, and keypair rotation). Because the AEAD tag authenti...

CVE-2026-13735: Authentication Bypass by Spoofing

Zephyr's WireGuard implementation in subsys/net/lib/wireguard/wgcrypto.c mishandled keepalive packets. In wgprocessdatamessage, any type-4 transport-data message whose payload was exactly 16 bytes an empty plaintext plus a bare Poly1305 tag, i.e. a keepalive was accepted and returned immediately,...

CVE-2026-58085

The wg(4) driver in FreeBSD contains a flaw where it fails to verify the success of the MAC verification step after dispatching a decrypt operation to the OpenCrypto framework (OCF) . This allows the driver to silently accept packets with an invalid Poly1305 authentication tag. A remote attacker ...
