Overview

CVE-2025-71145 is a high-severity vulnerability. It was published on January 23, 2026 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:

usb: phy: isp1301: fix non-OF device reference imbalance

A recent change fixing a device reference leak in a UDC driver

introduced a potential use-after-free in the non-OF case as the

isp1301_get_client() helper only increases the reference count for the

returned I2C device in the OF case.

Increment the reference count also for non-OF so that the caller can

decrement it unconditionally.

Note that this is inherently racy just as using the returned I2C device

is since nothing is preventing the PHY driver from being unbound while

in use.

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.
