Overview

CVE-2022-50519 is a medium-severity vulnerability. It was published on October 7, 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:

nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure

If creation or finalization of a checkpoint fails due to anomalies in the

checkpoint metadata on disk, a kernel warning is generated.

This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted

with panic_on_warn, does not panic. A nilfs_error is appropriate here to

handle the abnormal filesystem condition.

This also replaces the detected error codes with an I/O error so that

neither of the internal error codes is returned to callers.

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.
