Overview

CVE-2026-53152 is a medium-severity vulnerability. It was published on June 25, 2026 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:

mmc: dw_mmc-rockchip: Add missing private data for very old controllers

The really old controllers (rk2928, rk3066, rk3188) do not support UHS

speeds at all, and thus never handled phase data.

For that reason it never had a parse_dt callback and no driver private

data at all.

Commit ff6f0286c896 ("mmc: dw_mmc-rockchip: Add memory clock auto-gating

support") makes the private data sort of mandatory, because the init

function checks whether phases are configured internally or through the

clock controller.

This results in the old SoCs then experiencing NULL-pointer dereferences

when they try to access that private-data struct.

While we could have if (priv) conditionals in all places, it's way less

cluttery to just give the old types their private-data struct.

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.
