Summary
ntfs-3g vulnerabilities
Details
It was discovered that NTFS-3G had a heap buffer overflow when reading certain NTFS images. A local attacker could possibly use this issue to execute arbitrary code. (CVE-2026-42616)
It was discovered that NTFS-3G had multiple heap buffer overflows when processing certain NTFS images. A local attacker could possibly use these issues to execute arbitrary code. (CVE-2026-42617, CVE-2026-42618, CVE-2026-46569, CVE-2026-46570, CVE-2026-46572, CVE-2026-56135)
It was discovered that NTFS-3G had out-of-bounds reads when processing certain NTFS images. A local attacker could possibly use these issues to obtain sensitive information. (CVE-2026-46571, CVE-2026-56136)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
