Overview

CVE-2025-37967 is a medium-severity vulnerability. It was published on May 20, 2025 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:

usb: typec: ucsi: displayport: Fix deadlock

This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock

functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector

mutex is only locked if a connection is established and the partner pointer

is valid. This resolves a deadlock scenario where

ucsi_displayport_remove_partner holds con->mutex waiting for

dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

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.
