How to Fix CVE-2026-23056

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-2026-23056, 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: uacce: implement mremap in uacce_vm_ops to return -EPERM The current uacce_vm_ops does not support the mremap operation of vm_operations_struct. Implement .mremap to return -EPERM to remind users. The reason we need to explicitly disable mremap is that when the driver does not implement .mremap, it uses the default mremap method. This could lead to a risk scenario: An application might first mmap address p1, then mremap to p2, followed by munmap(p1), and finally munmap(p2). Since the default mremap copies the original vma's vm_private_data (i.e., q) to the new vma, both munmap operations would trigger vma_close, causing q->qfr to be freed twice(qfr will be set to null here, so repeated release is ok).
