TOCTOU in a local container runtime implies AV:L not AV:N; race timing gives AC:H, container access gives PR:L, and host escape justifies S:C with full C/I/A impact.

DescriptionCVE.org

NVIDIA Container Toolkit for Linux contains a vulnerability where an attacker could cause a time-of-check time-of-use race condition. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, and data tampering.

AnalysisAI

Privilege escalation and container escape in NVIDIA Container Toolkit for Linux (and the GPU Operator that bundles it) stem from a time-of-check to time-of-use (TOCTOU) race condition that can lead to arbitrary code execution, privilege escalation, and data tampering across a scope boundary. A low-privileged attacker who can win the race may break out of the intended isolation boundary of GPU-enabled containers. No public exploit has been identified at time of analysis, and the CVE is not listed in CISA KEV; NVIDIA is the reporting source via its product-security advisory 5850.

Technical ContextAI

NVIDIA Container Toolkit is the runtime shim (nvidia-container-runtime, nvidia-container-cli, and the runtime hook) that injects host GPU drivers, devices, and libraries into OCI/Docker/containerd containers; the GPU Operator (cpe:2.3:a:nvidia:gpu_operator) deploys this same toolkit at scale on Kubernetes. The root cause is CWE-367 (TOCTOU): the toolkit validates a resource - such as a path, device node, or mount source - at check time, but the resource is substituted (e.g., via a symlink swap or filesystem race) before it is actually used at operation time. Because the toolkit performs privileged operations while mediating between the container namespace and the host, winning this race lets an attacker redirect a trusted operation to attacker-controlled targets, which is the classic path to container-to-host escape and privilege escalation on GPU nodes.

RemediationAI

Patch available per vendor advisory - no exact fixed version was included in the input data, so obtain and apply the patched NVIDIA Container Toolkit and GPU Operator release specified in NVIDIA product-security advisory 5850 (https://github.com/NVIDIA/product-security/tree/main/2026/5850) and confirm the fixed version against the NVD entry (https://nvd.nist.gov/vuln/detail/CVE-2026-24260) before deploying; on Kubernetes, upgrade via the GPU Operator so all nodes receive the fixed toolkit consistently. As compensating controls until patched: restrict who can launch GPU containers by tightening RBAC and admission control so only trusted workloads get the nvidia runtime (trade-off: blocks some legitimate GPU jobs), avoid running GPU containers as privileged or with host mounts that overlap toolkit-managed paths (trade-off: may break workloads relying on host device access), and enforce read-only container root filesystems and drop CAP_SYS_ADMIN where feasible to reduce an attacker's ability to stage the symlink/path swap needed to win the race (trade-off: some GPU workloads require specific capabilities). Monitor node logs for unexpected mount/symlink activity around container startup as a detection aid.
