## CVEs this fix closes

| CVE | Priority | Title | CVSS | EPSS | Exploitation |
|---|---|---|---:|---:|---|
| [CVE-2026-42616](https://patchblox.com/security/data/cve/CVE-2026-42616.md) | High | In NTFS-3G before 2026.7.7, a heap buffer overflow exists in cat() in ntfscat.c that allows an attacker to corrupt heap memory in the ntfscat binary by crafting a malicious NTFS image. The overflow is triggered by reading a file. | 7.8 | 0.0017 |  |
| [CVE-2026-46569](https://patchblox.com/security/data/cve/CVE-2026-46569.md) | High | In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_copy_tail(), in libntfs-3g/index.c, that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by extending a directory, e.g., by creating a file. | 7.7 | 0.0016 |  |
| [CVE-2026-46570](https://patchblox.com/security/data/cve/CVE-2026-46570.md) | High | In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_index_walk_down() in libntfs-3g/index.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by reading the special crafted file metadata. | 8.1 | 0.0015 |  |
| [CVE-2026-46572](https://patchblox.com/security/data/cve/CVE-2026-46572.md) | High | In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_cut_tail() in libntfs-3g/index.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by creating a file in a specially crafted directory. | 7.4 | 0.0015 |  |
| [CVE-2026-42617](https://patchblox.com/security/data/cve/CVE-2026-42617.md) | High | In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ir_to_ib() in index.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by extending a directory, e.g., by creating a file. | 7.1 | 0.0015 |  |
| [CVE-2026-42618](https://patchblox.com/security/data/cve/CVE-2026-42618.md) | High | In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_decompress() in compress.c that allows an attacker to corrupt one byte of heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by reading the special crafted file. | 7.1 | 0.0015 |  |
| [CVE-2026-56135](https://patchblox.com/security/data/cve/CVE-2026-56135.md) | High | In NTFS-3G through 2026.2.25, a heap-based buffer overflow exists in the function build_inherited_id() in libntfs-3g/security.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by creating a file in a crafted directory. | 7.4 | 0.0014 |  |
| [CVE-2026-56136](https://patchblox.com/security/data/cve/CVE-2026-56136.md) | High | In NTFS-3G through 2026.2.25, an out-of-bounds read exists in ntfs_ir_nill() in libntfs-3g/index.c that allows an attacker to read possibly confidential information in an ntfs-3g process by crafting a malicious NTFS image. This read operation is triggered by creation of a file with a crafted name. | 7.1 | 0.0012 |  |
| [CVE-2026-46571](https://patchblox.com/security/data/cve/CVE-2026-46571.md) | Routine | In NTFS-3G before 2026.7.7, a out-of-bounds read exists in ntfs_fix_file_name() in libntfs-3g/reparse.c that allows an attacker to read possibly confidential information in ntfs-3g process memory by crafting a malicious NTFS image. The out-of-bounds read is triggered by a readlink on a corrupted file. | 5.5 | 0.0013 |  |
