How to Fix CVE-2026-64595

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-2026-64595, 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: HID: hid-lenovo-go: cancel cfg_setup work in hid_go_cfg_remove() hid_go_cfg_probe() initialises drvdata.go_cfg_setup and schedules it to run 2 ms later: INIT_DELAYED_WORK(&drvdata.go_cfg_setup, &cfg_setup); schedule_delayed_work(&drvdata.go_cfg_setup, msecs_to_jiffies(2)); cfg_setup() dereferences drvdata.hdev to issue MCU command requests. hid_go_cfg_remove() tears down sysfs and stops the HID device, but never drains the delayed work. If the device is unbound within the 2 ms scheduling delay (a probe failure rolling back via remove, or a fast rmmod after probe), the work fires after hid_destroy_device() has dropped its reference and released the underlying hdev struct, leaving cfg_setup() with a stale drvdata.hdev pointer. Mirror the sibling driver hid-lenovo-go-s.c, whose hid_gos_cfg_remove() already calls cancel_delayed_work_sync() on its analogous work, and drain go_cfg_setup at the top of hid_go_cfg_remove(). The cancel must come before guard(mutex)(&drvdata.cfg_mutex) because cfg_setup() acquires that mutex; reversing the order would deadlock.
