Kernel bypass risks in sandboxes

- Researchers warned kernel bypass failures inside containers or gVisor sandboxes can break isolation and expose sensitive data in high‑trust environments like trading. - The thread highlights attack paths where user‑space networking bypasses kernel controls, creating isolation gaps if the sandbox or control plane fails. - That risk is particularly relevant for firms using kernel bypass to reduce tail latency, since isolation failures can leak order or position data.
