When it is not, the parsing of the records proceeds into the wild.

The root cause is a missing consistency check after reading an MFT record : the bytes_in_use field should be less than the bytes_allocated field. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. (CVE-2019-9755) - In Tuxera ntfs-3g versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of service. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code.

A local user can take advantage of this flaw for local root privilege escalation. Jann Horn of Google Project Zero discovered that NTFS-3G, a read-write NTFS driver for FUSE, does not scrub the environment before executing modprobe with elevated privileges.
