Overview

CVE-2023-53316 is a high-severity vulnerability. It was published on September 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/msm/dp: Free resources after unregistering them

The DP component's unbind operation walks through the submodules to

unregister and clean things up. But if the unbind happens because the DP

controller itself is being removed, all the memory for those submodules

has just been freed.

Change the order of these operations to avoid the many use-after-free

that otherwise happens in this code path.

Patchwork: https://patchwork.freedesktop.org/patch/542166/

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.
