Overview

CVE-2022-50020 is a medium-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ext4: avoid resizing to a partial cluster size

This patch avoids an attempt to resize the filesystem to an

unaligned cluster boundary. An online resize to a size that is not

integral to cluster size results in the last iteration attempting to

grow the fs by a negative amount, which trips a BUG_ON and leaves the fs

with a corrupted in-memory superblock.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
