Overview

CVE-2025-22012 is a high-severity vulnerability. It was published on April 8, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, 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:

Revert "arm64: dts: qcom: sdm845: Affirm IDR0.CCTW on apps_smmu"

There are reports that the pagetable walker cache coherency is not a

given across the spectrum of SDM845/850 devices, leading to lock-ups

and resets. It works fine on some devices (like the Dragonboard 845c,

but not so much on the Lenovo Yoga C630).

This unfortunately looks like a fluke in firmware development, where

likely somewhere in the vast hypervisor stack, a change to accommodate

for this was only introduced after the initial software release (which

often serves as a baseline for products).

Revert the change to avoid additional guesswork around crashes.

This reverts commit 6b31a9744b8726c69bb0af290f8475a368a4b805.

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.
