Overview

CVE-2026-43480 is a medium-severity vulnerability. It was published on May 13, 2026 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:

ASoC: amd: acp3x-rt5682-max9836: Add missing error check for clock acquisition

The acp3x_5682_init() function did not check the return value of

clk_get(), which could lead to dereferencing error pointers in

rt5682_clk_enable().

Fix this by:

1. Changing clk_get() to the device-managed devm_clk_get().

2. Adding proper IS_ERR() checks for both clock acquisitions.

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.
