Overview

CVE-2023-53388 is a high-severity vulnerability. It was published on September 18, 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/mediatek: Clean dangling pointer on bind error path

mtk_drm_bind() can fail, in which case drm_dev_put() is called,

destroying the drm_device object. However a pointer to it was still

being held in the private object, and that pointer would be passed along

to DRM in mtk_drm_sys_prepare() if a suspend were triggered at that

point, resulting in a panic. Clean the pointer when destroying the

object in the error path to prevent this from happening.

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.
