Linux Kernel up to 6.14.1 ntfs3 size_add integer overflow

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.14.1. It has been classified as problematic. This affects the function size_add of the component ntfs3. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix a couple integer overflows on 32bit systems On 32bit systems the "off + sizeof(struct NTFS_DE)" addition can have an integer wrapping issue. Fix it by using size_add().

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2025-22081 since 12/29/2024. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 02/15/2026).

The vulnerability scanner Nessus provides a plugin with the ID 234884 (Debian dsa-5907 : affs-modules-6.1.0-33-4kc-malta-di - security update), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.15.180, 6.1.134, 6.6.87, 6.12.23, 6.13.11, 6.14.2 or 6.15-rc1 eliminates this vulnerability. Applying the patch 0922d86a7a6032cb1694eab0b44b861bd33ba8d5/1a14e9718a19d2e88de004a1360bfd7a86ed1395/0dfe700fbd3525f30a36ffbe390a5b9319bd009a/284c9549386e9883855fb82b730303bb2edea9de/0538f52410b619737e663167b6a2b2d0bc1a589d/4d0f4f42922a832388a0c2fe5204c0a1037ff786/5ad414f4df2294b28836b5b7b69787659d6aa708 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the databases at Tenable (234884), EUVD (EUVD-2025-11224) and CERT Bund (WID-SEC-2025-0844). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
