Linux Kernel ntfs input validation

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, which was classified as very critical, has been found in Linux Kernel (affected version unknown). This issue affects an unknown functionality of the component ntfs. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: ntfs: centalize $INDEX_ROOT header validation Add a dedicated helper to perform stricter validation of $INDEX_ROOT and use it for both directory inodes and named index inodes. This keeps the root size and header geometry checks consistent across both read paths.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2026-72204 since 08/09/2026. The exploitation is known to be easy. The attack may be initiated remotely.
