Overview

CVE-2023-53424 is a medium-severity vulnerability. It was published on September 18, 2025 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:

clk: mediatek: fix of_iomap memory leak

Smatch reports:

drivers/clk/mediatek/clk-mtk.c:583 mtk_clk_simple_probe() warn:

'base' from of_iomap() not released on lines: 496.

This problem was also found in linux-next. In mtk_clk_simple_probe(),

base is not released when handling errors

if clk_data is not existed, which may cause a leak.

So free_base should be added here to release base.

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.
