Overview

CVE-2022-50343 is a medium-severity vulnerability. It was published on September 16, 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:

rapidio: fix possible name leaks when rio_add_device() fails

Patch series "rapidio: fix three possible memory leaks".

This patchset fixes three name leaks in error handling.

- patch #1 fixes two name leaks while rio_add_device() fails.

- patch #2 fixes a name leak while rio_register_mport() fails.

This patch (of 2):

If rio_add_device() returns error, the name allocated by dev_set_name()

need be freed. It should use put_device() to give up the reference in the

error path, so that the name can be freed in kobject_cleanup(), and the

'rdev' can be freed in rio_release_dev().

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.
