CVE-2026-72188
Description
A flaw was found in the Linux kernel's NTFS filesystem driver. A remote attacker could craft a malicious NTFS image that, when processed, causes the ntfs_lookup_inode_by_name() function to return an unvalidated error-marked MFT (Master File Table) reference. This can lead to callers consuming a bogus error code, misinterpreting corrupted on-disk metadata, and potentially causing system instability or a denial of service.
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.
