Overview

CVE-2023-52660 is a medium-severity vulnerability. It was published on May 17, 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:

media: rkisp1: Fix IRQ handling due to shared interrupts

The driver requests the interrupts as IRQF_SHARED, so the interrupt

handlers can be called at any time. If such a call happens while the ISP

is powered down, the SoC will hang as the driver tries to access the

ISP registers.

This can be reproduced even without the platform sharing the IRQ line:

Enable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will

hang.

Fix this by adding a new field, 'irqs_enabled', which is used to bail

out from the interrupt handler when the ISP is not operational.

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-2023-52660?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2023-52660 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.
