How to Fix CVE-2026-68361

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-68361, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the Linux kernel, the following vulnerability has been resolved: hwmon: (corsair-psu) Stop device IO before calling hid_hw_stop hid_hw_stop() does not stop the device IO. This results in a race condition between hid_input_report() and the point immediately following the execution of hid_device_io_start() within corsairpsu_probe(). If the probe operation fails after "io start" has been initiated, this race condition will result in a uaf vulnerability [1]. CPU0 CPU1 ==== ==== corsairpsu_probe() hid_device_io_start() ... unlock driver_input_lock hid_hw_stop() kfree(hidraw) __hid_input_report() ... acquire driver_input_lock hid_report_raw_event() hidraw_report_event() ... access hidraw's list_lock // trigger uaf Consequently, when corsairpsu_probe() fails and hid_hw_stop() needs to be executed, the io_started flag is first cleared while holding the driver_input_lock to prevent potential race conditions involving input reports.
