Overview

CVE-2023-52882 is a medium-severity vulnerability. It was published on May 30, 2024 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: sunxi-ng: h6: Reparent CPUX during PLL CPUX rate change

While PLL CPUX clock rate change when CPU is running from it works in

vast majority of cases, now and then it causes instability. This leads

to system crashes and other undefined behaviour. After a lot of testing

(30+ hours) while also doing a lot of frequency switches, we can't

observe any instability issues anymore when doing reparenting to stable

clock like 24 MHz oscillator.

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.

How can CyberStrike help with CVE-2023-52882?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2023-52882 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
