Published Sep 17, 2026EPSS 0.34%

Overview

CVE-2026-90329 is a high-severity vulnerability. It was published on September 17, 2026 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: synchronize input before cleaning up a failed probe

hid_device_io_start() allows reports to run concurrently with probe. If

the probe subsequently fails, __hid_device_probe() releases driver

resources and clears hdev->driver without first excluding those report

callbacks.

For example, a report may enter hidraw_report_event() while the failure

path frees the associated hidraw object, leading to a use-after-free when

the report takes the object's list lock.

Stop input before performing failed-probe cleanup. This reacquires

driver_input_lock and waits for any report callback already in progress.

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.
