How Cube Sandbox Achieves Sub‑60ms Secure AI Agent Execution

Tencent Cloud open‑sources Cube Sandbox, a hardware‑isolated, sub‑60 ms startup sandbox for AI agents that is E2B‑compatible, dramatically reduces memory usage, supports continuous "think‑execute‑feedback" loops, and outperforms traditional Docker‑based sandboxes in speed, security, and scalability.

Linux Kernel SandBox Mode (SBM) Patch Enhances Memory Safety

Huawei engineer Petr Tesarik submitted a Linux kernel patch that adds SandBox Mode (SBM), an API confining kernel code to predefined memory regions, using hardware paging and CPU privilege levels to isolate components, detect out‑of‑bounds accesses, recover from violations, terminate the sandbox and return error codes such as -EFAULT, enabling continued execution.
