Overview

CVE-2024-53056 is a medium-severity vulnerability. It was published on November 19, 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/mediatek: Fix potential NULL dereference in mtk_crtc_destroy()

In mtk_crtc_create(), if the call to mbox_request_channel() fails then we

set the "mtk_crtc->cmdq_client.chan" pointer to NULL. In that situation,

we do not call cmdq_pkt_create().

During the cleanup, we need to check if the "mtk_crtc->cmdq_client.chan"

is NULL first before calling cmdq_pkt_destroy(). Calling

cmdq_pkt_destroy() is unnecessary if we didn't call cmdq_pkt_create() and

it will result in a NULL pointer dereference.

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.
