Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2026-80596

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-2026-80596, 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: Input: ims-pcu - only expose sysfs attributes on control interface When the driver was converted to use the driver core to instantiate device attributes (via .dev_groups in the usb_driver structure), the attributes started appearing on all interfaces bound to the driver. Since the ims-pcu driver manually claims the secondary data interface during probe, the driver core automatically creates the sysfs attributes for that interface as well. However, the driver only supports these attributes on the primary control interface. Data interfaces lack the necessary descriptors and internal state to handle these requests, and accessing them can lead to unexpected behavior or crashes. Fix this by updating the is_visible() callbacks for both the main and OFN attribute groups to verify that the interface being accessed is indeed the control interface.
