CVE-2021-1110
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 Linux kernel distributions on Jetson Xavier contain a vulnerability in camera firmware where a user can change input data after validation, which may lead to complete denial of service and serious data corruption of all kernel components.
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 confidenceA time-of-check-to-time-of-use (TOCTOU) vulnerability in the camera firmware of NVIDIA Jetson Xavier Linux kernel distributions allows attackers to modify input data after initial validation, causing denial of service and data corruption across kernel components.

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.
-
Identify Jetson hardware modelCheck /proc/cpuinfo or run 'cat /proc/device-tree/model' to confirm the device is a Jetson XavierAffected if Device is not a Jetson Xavier (vulnerability only affects Jetson Xavier)
-
Determine Jetson Linux versionRun 'cat /etc/nv_tegra_release' or check 'dpkg -l | grep nvidia-l4t-core' to obtain the installed Jetson Linux (L4T) version numberAffected if Version is 32.1 through 32.6.0 (versions >= 32.1 and < 32.6.1 are affected)
-
Check if camera subsystem is activeInspect /dev/video* devices or run 'v4l2-ctl --list-devices' to enumerate camera/video devicesAffected if Camera interfaces are exposed and accessible to untrusted processes
-
Verify camera firmware componentsCheck for camera-related kernel modules: 'lsmod | grep -i tegra' and review /dev/video* device permissions with 'ls -la /dev/video*'Affected if Camera firmware modules are loaded and device nodes have weak permissions (world-readable/writable)
Environment is affected if running Jetson Xavier with Jetson Linux version 32.1-32.6.0 and camera firmware interfaces are accessible to processes on the system.

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.
dbcve · scoped32.6.1
Apply the NVIDIA firmware/security patch for CVE-2021-1110; until patch availability, restrict access to camera interfaces to trusted processes only.
Jetson Linux 32.6.1 or later
- 1. Back up all critical data and configurations on the Jetson Xavier device
- 2. Download the Jetson Linux 32.6.1 (or later) firmware package from the official NVIDIA Jetson download center
- 3. Follow NVIDIA's standard Jetson Linux flashing procedure to update the device firmware
- 4. After flashing, verify the firmware version matches 32.6.1 or later using the command: cat /etc/nv_tegra_release
- 5. Re-enable camera functionality and verify all camera services are operating normally
