CVE-2022-30784
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 · uneditedA crafted NTFS image can cause heap exhaustion in ntfs_get_attribute_value 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 confidenceA vulnerability in NTFS-3G versions through 2021.8.22 allows a crafted NTFS image to cause heap exhaustion in the ntfs_get_attribute_value function. When mounting a maliciously constructed NTFS filesystem, the driver attempts excessive memory allocation, leading to resource exhaustion and potential denial of service.

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.
-
Check if NTFS-3G is installedRun 'ntfs-3g --version' or 'which ntfs-3g' to verify the utility is present on the systemAffected if NTFS-3G is not installed means not affected by this vulnerability
-
Identify the installed NTFS-3G versionRun 'ntfs-3g --version' to display the version number, or use 'dpkg -l ntfs-3g' on Debian-based systems, or 'rpm -qi ntfs-3g' on Fedora-based systemsAffected if Version is not displayed or the package is not found indicates NTFS-3G is not in use
-
Compare version against affected rangeReview the output from step 2. The vulnerability affects versions through 2021.8.22. If the version shown is 2021.8.22 or earlier, the installation is within the affected rangeAffected if Installed version is 2021.8.22 or earlier (for example, 2021.4.22, 2020.10.9, etc.)
-
Determine if NTFS mounting capability is in useCheck for ntfs-3g in running processes, mounted filesystems reported by 'df -T', or system services that may auto-mount NTFS devicesAffected if NTFS-3G is actively used to mount NTFS filesystems, particularly from untrusted sources, increases exposure to the vulnerability
A system is affected if NTFS-3G version 2021.8.22 or earlier is installed and is used to mount NTFS filesystems, as the heap exhaustion flaw triggers when mounting a crafted malicious NTFS image.

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 · scopedUpdate NTFS-3G to version 2021.8.22 or later. Avoid mounting untrusted or unknown NTFS images from unverified sources.
NTFS-3G version 2022.10.3 or later
- 1. Check the currently installed NTFS-3G version using: `ntfs-3g --version`
- 2. Update the NTFS-3G package to the latest available version using your distribution's package manager
- 3. For Debian: `sudo apt update && sudo apt install ntfs-3g`
- 4. For Fedora: `sudo dnf update ntfs-3g`
- 5. Verify the updated version is newer than 2021.8.22
