In the Linux kernel, the following vulnerability has been resolved: ntfs: reject invalid empty mapping pairs Reject an attribute with empty mapping… (CVE-2026-89613)
A vulnerability in the Linux kernel's NTFS driver has been resolved. The flaw involved accepting attributes with empty mapping pairs that had inconsistent highest VCN and size values. This could lead to improper handling of NTFS attributes.
AI Analysis
Technical Summary
The Linux kernel contained a vulnerability in its NTFS filesystem driver where attributes with empty mapping pairs were not properly rejected if they had inconsistent highest Virtual Cluster Number (VCN) and size. This flaw was addressed by adding validation to reject such invalid empty mapping pairs, preventing potential inconsistencies in NTFS attribute processing.
Potential Impact
The vulnerability could cause the kernel to improperly process NTFS attributes with invalid empty mapping pairs, potentially leading to incorrect filesystem behavior or stability issues. No specific exploitation or impact details are provided in the available data.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to reject invalid empty mapping pairs in NTFS attributes. Users should apply the official kernel update that includes this patch once available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory for current remediation guidance.
