Overview

CVE-2023-52511 is a medium-severity vulnerability. It was published on March 2, 2024 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

spi: sun6i: reduce DMA RX transfer width to single byte

Through empirical testing it has been determined that sometimes RX SPI

transfers with DMA enabled return corrupted data. This is down to single

or even multiple bytes lost during DMA transfer from SPI peripheral to

memory. It seems the RX FIFO within the SPI peripheral can become

confused when performing bus read accesses wider than a single byte to it

during an active SPI transfer.

This patch reduces the width of individual DMA read accesses to the

RX FIFO to a single byte to mitigate that issue.

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-2023-52511?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2023-52511 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.
