Using a VM to Contain an AI Agent

Bruce Schneier reports GPT 5.6-Cyber repeatedly succeeded inside VM sandboxes, warning that off-the-shelf VMs cannot contain modern cyber-capable AI agents.

In a Schneier on Security post, Bruce Schneier reports that GPT 5.6-Cyber succeeded frequently and in telling ways against a VM-based sandbox, arguing that sandboxing quality for capable AI agents - and the whole software stack they interact with - must be reassessed. He contends that an off-the-shelf VM offers too much attack surface to contain a modern, cyber-capable agent, and that even innocuous features such as running with a display add exploitable surface. The post reflects an observed evaluation outcome rather than a formal disclosure.

Isolated-vm Flaw Lets Sandboxed JavaScript Escape to Host for Potential RCE

Critical type-confusion flaw in isolated-vm Node.js sandbox (GHSA-864f-rcv7-6rh4) enables guest-to-host escape and potential RCE; fixed in 6.2.0 and 7.0.1.

Endor Labs researcher Cristian-Alexandru Staicu found a type confusion in the ExternalCopy component's handling of the transferList option in isolated-vm, letting sandboxed JavaScript corrupt host-process memory and escalate from controlled-address crashes to full control-flow hijack of the host, i.e., potential remote code execution. The flaw, tracked as GHSA-864f-rcv7-6rh4 with no CVE yet, affects all versions through 7.0.0 of the library, which sees nearly 1 million npm downloads weekly. It was patched in versions 6.2.0 and 7.0.1 released earlier in August 2026, and full exploit details are withheld to prevent attacks. The V8 Isolate boundary itself held; the failure was in the C++ marshalling code bridging host and guest.

DeepSeek Harness Flaw Let AI Agents Disable Their Own File Sandbox Without Approval

DeepSeek Harness (CVE-2026-82533, CVSS 9.4) let AI coding agents disable their own sandbox via an unauthenticated local API; fixed in 0.1.2-alpha.2.

DeepSeek Harness versions 0.1.1-rc.2 and earlier allowed a sandboxed AI coding agent to turn off its own OS sandbox by calling the tool's unauthenticated local web interface, tracked as CVE-2026-82533 with a 9.4 CVSS from VulnCheck. A single command set the agent session to danger-full-access mode, removing sandboxing and approval prompts, and OX Research verified writes escaped the workspace. The interface trusted the client-supplied Host header with no authentication and could also return a session's entire conversation log. The fix adds a one-time token and signed-cookie check; the first npm release carrying it is 0.1.2-alpha.2, with 0.1.2-rc.1 current.

$1 Million Sandbox Challenge Uncovers Linux Kernel Flaws

Vercel's $1M sandbox challenge surfaced two Linux kernel networking defects—one leaking host kernel memory, one crashing hosts—with CVEs pending.

Vercel ran a two-week, $1 million sandbox escape challenge (Aug 18–Sep 1) on its Firecracker-based microVM sandbox, receiving 1,285 reports and committing ~$325k in payouts (1 Critical, 7 High, 15 Medium, 49 Low validated so far). No attacker accessed real customer data. The most important filing found two independent Linux kernel networking stack defects—one leaks host kernel memory, the other deterministically crashes the host—with wide implications for cloud providers isolating workloads via the same kernel layer. Fixes are under private review with CVEs pending; Vercel also plans to open-source its agentic report-triage agent built on the Eve framework running Kimi K3.

VU#687587: AOMEI Backupper amwrtdrv.sys local privilege escalation vulnerability allows arbitrary writes to physical disks

AOMEI Backupper 8.4.0 driver flaw CVE-2026-12780 lets unprivileged users write physical disks and execute UEFI code, bypassing HVCI and EDR.

CERT/CC issued VU#687587 for CVE-2026-12780, an incorrect permission assignment (CWE-732) in the amwrtdrv.sys kernel driver shipped with AOMEI Backupper 8.4.0. The driver exposes a world-accessible device object without a security descriptor, allowing any unprivileged user to write arbitrary physical disk sectors; with Secure Boot disabled, an attacker can modify the GPT and inject a UEFI payload that executes before the OS loads, bypassing HVCI, EDR, Windows Defender and Hyper-V isolation. On TPM-only BitLocker configurations the attack can capture Volume Master Key material during pre-boot. AOMEI has shipped patches; users who cannot update should uninstall the software or disable the amwrtdrv.sys service, and enabling Secure Boot adds defense in depth.

CVE-2026-89775: Guest-to-Host Escape in KVM/arm64

Disclosed CVE-2026-89775 lets a guest VM escape to the host on KVM/arm64 systems with nested virtualization enabled.

Researcher Hyunwoo Kim disclosed CVE-2026-89775, a guest-to-host escape in KVM/arm64, after the embargo agreed with linux-distros maintainers expired. The root cause is a type truncation of the stage-1 walk level that makes a size computation return 0, the value meaning 'size unknown'. The VNCR pseudo-TLB invalidation path then interprets that 0 as a valid value on ARM64 hosts where nested virtualization is enabled.

An Empirical Analysis of CodeQL False Positives and Query Refinements for Java Vulnerabilities

Study of 167 Java CVE instances finds CodeQL false positives follow recurring patterns; query refinements remove 81.8% of reviewed ones.

Researchers ran CodeQL's Java security query suite on 167 CVE instances from 110 projects, manually reviewing 500 sampled false-positive paths and building a five-category taxonomy led by Missed Path Constraint or Sanitization (36.6%), Benign Execution Context (29.4%), and Missing Trust Boundary Modeling (27.6%). Guided by the taxonomy, query-level refinements removed 81.8% of reviewed false positives and 15.8% of reported paths across the selected queries while retaining 7 of 8 true positives. To address generalization, agentic coding tools given the refinement patterns as templates adapted them to new projects successfully in 56% and 62% of tasks, versus 28% without guidance.
