Overview

CVE-2025-22097 is a high-severity vulnerability. It was published on April 16, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

drm/vkms: Fix use after free and double free on init error

If the driver initialization fails, the vkms_exit() function might

access an uninitialized or freed default_config pointer and it might

double free it.

Fix both possible errors by initializing default_config only when the

driver initialization succeeded.

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.
