Background

The Kernel package is a fundamental component of the Linux operating system. It provides the core functionality and interfaces for the system, including device drivers, process management, and file systems. The ntfs module within the Kernel package is responsible for handling the NTFS file system commonly used by Windows. It allows Linux systems to read and write NTFS partitions. However, a vulnerability has been discovered in the ntfs module related to the allocation size parameter.
