Background
The ext4 package is a file system driver for the Linux Kernel. It provides support for the fourth extended file system (ext4), which is the default file system for many Linux distributions. The ext4 file system is widely used due to its improved performance and reliability compared to its predecessor, ext3. However, like any software, ext4 is susceptible to vulnerabilities that can impact its functionality and security.
Vulnerability Detail
The vulnerability in ext4 involves a check that can result in a false positive report of incorrect used inodes. Inodes are data structures used by file systems to store metadata about files, such as permissions, timestamps, and file size. The incorrect report of used inodes can lead to incorrect assumptions about the file system's state, potentially causing data corruption or other unexpected behavior. This vulnerability was introduced in version v4.18 of the Linux Kernel and has been fixed in version v5.11.20.
How To Fix
