Background
The Linux Kernel is a widely used open-source monolithic Unix-like computer operating system kernel. It provides the essential services to enable communication between hardware and software components of a computer system. The ext2 file system is the second extended file system for the Linux Kernel, offering features such as support for large file systems and file sizes. However, a vulnerability has been identified in the ext2 file system that affects the computation of the maximum file size.
Vulnerability Detail
The vulnerability in the ext2 file system arises from an incorrect computation of the maximum file size. This flaw can potentially lead to file system corruption or denial of service attacks. By exploiting this vulnerability, an attacker could manipulate the file system to exceed its intended limits, causing data corruption or system instability. The vulnerability was introduced in version v4.19.31 of the Linux Kernel and has been fixed in version v4.19.238.
How To Fix
