Overview

CVE-2024-27041 is a medium-severity vulnerability. It was published on May 1, 2024 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:

drm/amd/display: fix NULL checks for adev->dm.dc in amdgpu_dm_fini()

Since 'adev->dm.dc' in amdgpu_dm_fini() might turn out to be NULL

before the call to dc_enable_dmub_notifications(), check

beforehand to ensure there will not be a possible NULL-ptr-deref

there.

Also, since commit 1e88eb1b2c25 ("drm/amd/display: Drop

CONFIG_DRM_AMD_DC_HDCP") there are two separate checks for NULL in

'adev->dm.dc' before dc_deinit_callbacks() and dc_dmub_srv_destroy().

Clean up by combining them all under one 'if'.

Found by Linux Verification Center (linuxtesting.org) with static

analysis tool SVACE.

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.
