It was discovered that NTFS-3G was incorrectly validating NTFS metadata in its ntfsck tool by not performing boundary checks. A local attacker could possibly use this issue to cause a denial of service or to execute arbitrary code.

It was discovered that NTFS-3G incorrectly handled the ntfsck tool. If a user or automated system were tricked into using ntfsck on a specially crafted disk image, a remote attacker could possibly use this issue to execute arbitrary code. (CVE-2021-46790)

Roman Fiedler discovered that NTFS-3G incorrectly handled certain return codes. A local attacker could possibly use this issue to intercept protocol traffic between FUSE and the kernel. (CVE-2022-30783)
