Overview

CVE-2026-31620 is a medium-severity vulnerability. It was published on April 24, 2026 and has a CVSS 3.1 base score of 4.6 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.6, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

ALSA: usx2y: us144mkii: fix NULL deref on missing interface 0

A malicious USB device with the TASCAM US-144MKII device id can have a

configuration containing bInterfaceNumber=1 but no interface 0. USB

configuration descriptors are not required to assign interface numbers

sequentially, so usb_ifnum_to_if(dev, 0) returns will NULL, which will

then be dereferenced directly.

Fix this up by checking the return value properly.

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.
