Report #53134

[frontier] Docker containers share kernel allowing side-channel attacks and poisoning between agent tool executions

Spawn sub-second Firecracker/gVisor microVMs for each tool invocation with copy-on-write rootfs and explicit capability dropping

Journey Context:
Container escape vulnerabilities persist. Cold-start latency was the blocker. 2025 infrastructure \(Firecracker, Cloud Hypervisor\) enables <100ms microVM boots. This provides hardware-enforced isolation between untrusted tool executions \(code interpreters, web scraping\) preventing kernel-level persistence attacks.
