CVE-2026-24260
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA Container Toolkit for Linux contains a time-of-check time-of-use (TOCTOU) race condition vulnerability. An attacker can exploit the time gap between checking a condition and using the result to modify system state, potentially achieving code execution, privilege escalation, and data tampering.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify NVIDIA Container Toolkit is installedRun 'nvidia-container-cli --version' or check for package using your package manager (e.g., 'dpkg -l | grep nvidia-container-toolkit' or 'rpm -qa | grep nvidia-container-toolkit')Affected if The package is installed and the version falls within any affected range (compare to vendor advisories)
-
Identify the installed version numberExecute 'nvidia-container-cli --version' or 'nvidia-container-runtime --version' to retrieve the exact version stringAffected if The version number is lower than the fixed version published in NVIDIA's security bulletin for CVE-2026-24260
-
Confirm the toolkit is actively usedCheck if containers are running with NVIDIA runtime: 'docker ps' and inspect container configs for '--gpus' flag or 'nvidia' runtime reference in /etc/docker/daemon.jsonAffected if The NVIDIA runtime is configured as default or commonly used for container launches, exposing the TOCTOU window during container operations
-
Inspect container operation logs for anomaliesReview container runtime logs and NVIDIA container toolkit logs in /var/log/ for suspicious timing gaps or unexpected operations around container creation/launchAffected if Log entries show inconsistencies between permission checks and actual container execution that could indicate race condition exploitation
You are affected if NVIDIA Container Toolkit for Linux is installed with a version prior to the patched release and the toolkit runtime is actively used for container operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper synchronization mechanisms (e.g., file locking, atomic operations) to eliminate the race window between check and use operations in the affected code path.
