CVE-2024-41019: fs/ntfs3: Validate ff offset

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate ff offset This adds sanity checks for ff offset. There is a check on rt->first_free at first, but walking through by ff without any check. If the second ff is a large offset. We may encounter an out-of-bound read.

Security readout for executives and security teams

Plain-English summary

A flaw in Linux’s NTFS3 filesystem driver can read beyond valid memory while processing an invalid filesystem offset. Successful abuse requires local, low-privileged access and no user interaction. The supplied CVSS score is 7.8, reflecting potentially serious confidentiality, integrity, and availability consequences, although the sources do not document a demonstrated real-world impact.

Executive priority

Treat as a high-priority kernel maintenance issue on systems that process NTFS media or images from untrusted sources. Accelerate remediation where local users can influence mounts. For other systems, validate NTFS3 usage and vendor patch status before assigning emergency priority; the supplied evidence does not show active exploitation.

Technical view

NTFS3 initially validates rt->first_free but previously followed subsequent ff offsets without equivalent bounds checks. A large second offset could cause an out-of-bounds read in kernel context. Upstream stable commits add sanity checks. The source bundle identifies affected Linux versions spanning 5.15 through 6.11, but organizations should confirm vendor backport status rather than relying only on version numbers.

Likely exposure

Exposure is greatest where affected kernels use NTFS3 and local users or services can cause untrusted NTFS filesystems to be processed. Systems without NTFS3 use or without that local access path are less exposed. The supplied affected-version data contains mixed release and commit identifiers, so distribution-specific verification is necessary.

Exploitation context

The CVSS vector describes local access, low complexity, low privileges, no user interaction, and unchanged scope. The supplied sources do not establish remote exploitation, public weaponization, or exploitation in the wild. CVE-2024-41019 is not identified as a CISA KEV entry in the bundle.

Researcher notes

The documented primitive is an out-of-bounds read caused by insufficient validation of chained ff offsets. Multiple stable-branch commits are supplied, indicating branch-specific fixes. The sources do not provide a CWE classification, proof of code execution, crash details, exploit reliability, or evidence supporting the full theoretical CVSS impact. Avoid inferring those outcomes without additional evidence.

Mitigation direction

  • Upgrade to a vendor kernel containing the applicable upstream stable fix or confirmed backport.
  • Consult distribution guidance because package versions may include fixes without matching upstream version numbers.
  • Reduce opportunities for untrusted users or services to mount or process NTFS filesystems.
  • If immediate patching is impossible, evaluate disabling unused NTFS3 functionality under normal change controls.

Validation and detection

  • Inventory kernel and distribution package versions across systems that load or use NTFS3.
  • Confirm the applicable fix commit or vendor backport is present in deployed kernel sources or advisories.
  • Identify workflows allowing local users or services to supply or mount untrusted NTFS filesystems.
  • After updating, verify the intended kernel is running and NTFS workflows still operate correctly.
