Overview

CVE-2024-44967 is a high-severity vulnerability. It was published on September 4, 2024 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/mgag200: Bind I2C lifetime to DRM device

Managed cleanup with devm_add_action_or_reset() will release the I2C

adapter when the underlying Linux device goes away. But the connector

still refers to it, so this cleanup leaves behind a stale pointer

in struct drm_connector.ddc.

Bind the lifetime of the I2C adapter to the connector's lifetime by

using DRM's managed release. When the DRM device goes away (after

the Linux device) DRM will first clean up the connector and then

clean up the I2C adapter.

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.
