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 · unedited
A crafted NTFS image can cause a heap-based buffer overflow in ntfs_check_log_client_array in NTFS-3G through 2021.8.22.

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 · high confidence

A heap-based buffer overflow vulnerability exists in the ntfs_check_log_client_array function of NTFS-3G (versions through 2021.8.22). The flaw is triggered when parsing a specially crafted NTFS image, allowing an attacker to overwrite heap memory and potentially achieve code execution or cause a denial of service.

MitigationUpdate NTFS-3G to version 2021.8.22 or later. Avoid mounting untrusted NTFS images from unknown sources until the patch is applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify NTFS-3G is installed
    Run 'ntfs-3g --version' or check your package manager for the ntfs-3g package (e.g., 'dpkg -l | grep ntfs-3g' on Debian-based systems, 'rpm -qa | grep ntfs-3g' on RPM-based systems)
    Affected if NTFS-3G is not installed on the system - no action needed. If installed, proceed to version check.
  2. Determine installed NTFS-3G version
    Run 'ntfs-3g --version' to see the exact version number, or use package manager queries: 'dpkg -s ntfs-3g' (Debian) or 'rpm -qi ntfs-3g' (Fedora/RHEL)
    Affected if The displayed version is 2021.8.22 or earlier, or the version cannot be determined but the package is installed on an affected distribution (Debian 9/10/11, Fedora 35/36)
  3. Confirm NTFS-3G is actively used
    Check if NTFS-3G is being used to mount NTFS filesystems - look for ntfs-3g processes ('ps aux | grep ntfs-3g'), check /proc/mounts for NTFS mounts, or review system logs for recent NTFS mount operations
    Affected if NTFS-3G is installed and being used to mount or access NTFS filesystems. The vulnerability is triggered when parsing NTFS images, particularly those from untrusted sources.
  4. Check for untrusted NTFS image handling
    Review any automated or manual processes that mount NTFS images from external or untrusted sources. Check for scripts or tools that use ntfs-3g to open image files (.img, .vhd, or disk images)
    Affected if The system mounts or parses NTFS images from unknown or untrusted sources using NTFS-3G

A user is affected if NTFS-3G version 2021.8.22 or earlier is installed and actively used to mount or parse NTFS images, especially from untrusted sources.

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 · scoped
Upgrade available Upgrade to a release after 2021.8.22
Interim mitigation

Update NTFS-3G to version 2021.8.22 or later. Avoid mounting untrusted NTFS images from unknown sources until the patch is applied.

Recommended fix High confidence

NTFS-3G version 2022.10.3 or later (or the equivalent patched version in your distribution's repository)

  1. Update the ntfs-3g package to a version newer than 2021.8.22 (e.g., 2022.10.3 or later)
  2. For Debian systems: Run 'apt update && apt install ntfs-3g' to get the fixed package
  3. For Fedora systems: Run 'dnf update ntfs-3g' to get the fixed package
  4. Verify the installed version with 'ntfs-3g --version' to confirm it is above 2021.8.22
Caveat Minimal risk; NTFS-3G is a mature stable tool. As a precaution, test with non-critical NTFS images first.
