Overview

CVE-2023-52645 is a medium-severity vulnerability. It was published on April 17, 2024 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, 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:

pmdomain: mediatek: fix race conditions with genpd

If the power domains are registered first with genpd and *after that*

the driver attempts to power them on in the probe sequence, then it is

possible that a race condition occurs if genpd tries to power them on

in the same time.

The same is valid for powering them off before unregistering them

from genpd.

Attempt to fix race conditions by first removing the domains from genpd

and *after that* powering down domains.

Also first power up the domains and *after that* register them

to genpd.

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.
