How to Fix CVE-2026-90249

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-2026-90249, 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: iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes The IIO core does not filter duplicate writes to the event enable attribute, so writing the same value twice invokes write_event_config() twice. Enabling twice leaks a runtime PM reference, preventing the device from ever suspending again; disabling twice underflows the usage count and triggers a "Runtime PM usage count underflow" warning. Bail out early when the requested state matches the current state. While at it, switch to pm_runtime_resume_and_get() so a failed resume is propagated to userspace instead of silently marking the event enabled.
