Overview

CVE-2025-38253 is a high-severity vulnerability. It was published on July 9, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. 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:

HID: wacom: fix crash in wacom_aes_battery_handler()

Commit fd2a9b29dc9c ("HID: wacom: Remove AES power_supply after extended

inactivity") introduced wacom_aes_battery_handler() which is scheduled

as a delayed work (aes_battery_work).

In wacom_remove(), aes_battery_work is not canceled. Consequently, if

the device is removed while aes_battery_work is still pending, then hard

crashes or "Oops: general protection fault..." are experienced when

wacom_aes_battery_handler() is finally called. E.g., this happens with

built-in USB devices after resume from hibernate when aes_battery_work

was still pending at the time of hibernation.

So, take care to cancel aes_battery_work in wacom_remove().

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.
