Overview

CVE-2025-39696 is a high-severity vulnerability. It was published on September 5, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

ALSA: hda: tas2781: Fix wrong reference of tasdevice_priv

During the conversion to unify the calibration data management, the

reference to tasdevice_priv was wrongly set to h->hda_priv instead of

h->priv. This resulted in memory corruption and crashes eventually.

Unfortunately it's a void pointer, hence the compiler couldn't know

that it's wrong.

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.
