CVE-2026-72201

Description

A flaw was found in the Linux kernel's New Technology File System (NTFS) implementation. This vulnerability arises from insufficient validation of index entries when reading index roots or blocks from disk. An attacker could potentially craft a malicious NTFS filesystem, which, when processed by the kernel, might lead to data integrity issues or system instability by bypassing intended checks during file system operations.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
